Description

Technical Field

[0001] This invention specifically relates to a strong X-ray radiation source and method for blocking Z-pinch spatter, used in Z-pinch-related experiments to block Z-pinch spatter generated by Z-pinch plasma implosion using a rotating disk. Background Technology

[0002] Z-pinch technology refers to the use of pulsed power technology to generate a large MA-level current that, when flowing through a filament array or gas load, heats and ionizes the load to form plasma. Under the action of the Lorentz force generated by the large current flowing through its own axis, the plasma accelerates towards the axis and implodes, forming a high-temperature, high-density plasma at the center of the implosion. Ultimately, it produces pulsed strong X-rays through linear radiation, composite radiation, and bremsstrahlung radiation.

[0003] Z-pinch, as a powerful X-ray radiation source, has important applications in inertial confinement fusion, X-ray thermodynamics, laboratory astrophysics, high-energy-density physics, and materials properties. However, after the emission of Z-pinch X-rays, the rebound of the plasma column generates Z-pinch spatter with speeds up to 10 km / s. This spatter can contaminate numerous optical diagnostic devices used in Z-pinch experiments, reducing their lifespan, lowering their measurement accuracy, and even causing diagnostic system malfunctions. Furthermore, the generation of Z-pinch spatter can also interfere with the normal operation of X-ray radiation effect experiments. Therefore, effective measures are needed to block the Z-pinch spatter generated by the implosion of the Z-pinch plasma.

[0004] Currently used Z-pinch spatter blocking technology is generally a fast valve blocking technology. The design concept of this technology is to synchronously trigger the drive device of the fast valve during X-ray emission, causing it to accelerate in a straight line for tens of microseconds and stop at the diagnostic window, thus blocking the Z-pinch spatter before it reaches the window. This technology requires the fast valve to begin accelerating only at the moment of X-ray emission, therefore placing very stringent requirements on the drive device. Furthermore, the maximum speed achievable by the fast valve is limited, and it cannot provide adequate protection for diagnostic windows that are close to the Z-pinch. In addition, because the high-speed moving fast valve needs to stop at the diagnostic window, this technology also places very stringent requirements on the braking system, requiring it to have sufficient mechanical strength and to prevent the fast valve from rebounding. Due to the limitations of the drive device and braking system, the maximum speed achievable by the fast valve is limited, and it is accompanied by significant time jitter, thus limiting its effectiveness in blocking Z-pinch spatter. Summary of the Invention

[0005] The purpose of this invention is to address the technical problem that existing Z-pinch spatter blocking technologies are insufficient to protect diagnostic equipment and also affect the normal conduct of X-ray radiation effect experiments. The invention provides a strong X-ray radiation source and generation method that can block Z-pinch spatter, thereby rapidly blocking the optical channel after Z-pinch X-rays are incident on the diagnostic equipment, thus achieving the purpose of protecting the Z-pinch diagnostic equipment.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A high-intensity X-ray radiation source capable of blocking Z-pinch sputtering includes a photodetector, a delay timer mounted on an external experimental platform, a light-limiting slit, a laser, and a Z-pinch load.

[0008] Its special feature is that it also includes a Z-pinch splash blocking device;

[0009] The Z-pinch splash blocking device includes a clamp, a mounting bracket, a disc mounted on the mounting bracket, and a motor;

[0010] The light-limiting slit is vertically positioned on the X-ray path emitted from the Z-pinch load;

[0011] The photodetector is positioned perpendicularly to the laser beam path emitted by the laser.

[0012] The disk is located between the light-limiting slit and the Z-pinch load, as well as the laser and photodetector, and is connected to the drive shaft of the motor via a clamp; the disk has an opening, the size of which is larger than the size of the light-limiting slit, to allow the laser and X-rays to pass through;

[0013] The photodetector is mounted on the mounting bracket to emit a trigger signal and triggers the emission of X-rays from within the Z-pinch load by a time delay.

[0014] The delay timer is used to delay the trigger signal of the photodetector until the light-limiting slit and the opening overlap or coincide, and then send it to the Z-pinch load.

[0015] Furthermore, thickened structures (11) are provided on both sides of the center of the disk to enhance the stress of the disk;

[0016] The thickened structure (11) is matched with the fixture.

[0017] Furthermore, the device also includes a counterweight (10) for balancing the center of mass of the disk to the center of the disk.

[0018] The counterweights (10) are located on both sides of the opening near the center of the disk.

[0019] Furthermore, the light-limiting slit has a rectangular structure;

[0020] The opening is a concave or V-shaped structure with an opening angle θ of 1° to 10°; or the opening is a rectangular structure.

[0021] Meanwhile, this invention provides a high-intensity X-ray radiation source capable of blocking Z-pinch sputterings, comprising a photodetector, a time delay device mounted on an external experimental platform, a light-limiting slit, a laser, and a Z-pinch load.

[0022] Its special feature is that it also includes a Z-pinch splash blocking device;

[0023] It also includes a Z-pinch splash blocking device comprising a clamp, a mounting bracket, a disc mounted on the mounting bracket, and a motor;

[0024] The light-limiting slit is vertically positioned on the X-ray path emitted from the Z-pinch load;

[0025] The photodetector is positioned perpendicularly to the laser beam path emitted by the laser.

[0026] The disk is located between the light-limiting slit and the Z-pinch load, as well as the laser and photodetector, and is connected to the drive shaft of the motor via a clamp; the disk has two openings for the laser and X-rays to pass through; the two openings in opposite directions are located on the same diameter of the disk, and the size of the openings is larger than the size of the light-limiting slit.

[0027] The photodetector is mounted on the mounting bracket to emit a trigger signal and triggers the emission of X-rays from within the Z-pinch load by a time delay.

[0028] The delay timer is used to delay the trigger signal of the photodetector until the light-limiting slit and the opening overlap or coincide, and then send it to the Z-pinch load.

[0029] Furthermore, thickened structures (11) are provided on both sides of the center of the disk to enhance the stress of the disk;

[0030] The thickened structure (11) is matched with the fixture.

[0031] Furthermore, the light-limiting slit has a rectangular structure;

[0032] The opening is a concave or V-shaped structure with an opening angle θ of 1° to 10°; or the opening is a rectangular structure.

[0033] In addition, the present invention also provides a method for generating strong X-rays that can block Z-pinch spatter, characterized by comprising the following steps:

[0034] 1) Determine the disk radius and opening angle based on the size of the light-limiting slit;

[0035] 2) Calculate the rotational speed of the disk;

[0036] 3) Prepare a strong X-ray radiation source that can block the above-mentioned Z-pinch sputtering material;

[0037] 4) Turn on the laser and start the motor to drive the disk to rotate. After the disk rotates steadily, pre-start the Z-pinch load to keep it in the pre-trigger state.

[0038] When the opening rotates to a position opposite to the photodetector, the photodetector receives the laser signal emitted by the laser and sends a trigger signal to the delay timer.

[0039] When the opening rotates to a position opposite to the light-limiting slit, the trigger signal, after being delayed by the delay timer, synchronously triggers the burst emission of X-rays from the Z-pinch load. The X-rays enter the light-limiting slit through the opening, and then the disk blocks the light-limiting slit, completing the blocking of Z-pinch spatter.

[0040] Furthermore, step 2) specifically involves:

[0041] In step 1), the light-limiting slit has a rectangular structure;

[0042] The dimensions of the disk are determined based on the light-limiting slit using the following formula:

[0043]

[0044] In the formula: R is the radius of the disk, θ is the opening angle, and r is the width of the light-limiting slit. l The slit length is limited.

[0045] Furthermore, step 2) specifically involves:

[0046] Based on the velocity v of the Z-pinch spatter, the distance L from the center of the Z-pinch load implosion to the light-limiting slit, and the opening angle, the rotational speed n of the disk is calculated using the following formula:

[0047]

[0048] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

[0049] 1. This invention can block strong X-ray radiation sources of Z-pinch spatter without requiring acceleration in a short time, i.e., it does not require pulse power devices, has low requirements for the drive system, and does not require braking devices, i.e., it can decelerate naturally after completing the blocking task.

[0050] 2. This invention can block strong X-ray radiation sources of Z-pinch splashes, and has a superior ability to block Z-pinch splashes. It can also effectively block Z-pinch splashes for diagnostic equipment that is closer to the center of the Z-pinch implosion and has a larger light-limiting slit.

[0051] 3. This invention can block strong X-ray radiation sources of Z-pinch sputtering material. The shape, size, and rotation speed of the disk can be flexibly selected according to the size of the light-limiting slit being blocked and the distance between the slit and the Z-pinch.

[0052] 4. This invention can block strong X-ray radiation sources of Z-pinch spatter. When optimizing the disk, it proposes to set counterweights or thicken the structure at specific positions to balance the center of mass, thereby achieving the effect of reducing stress and improving blocking ability.

[0053] 5. The present invention provides a method for blocking the generation of strong X-rays from Z-pinch sputterings. It uses the periodic electrical signal output by a photodetector as a synchronous trigger signal to actively trigger the internal burst emission of X-rays from the Z-pinch load, thereby reducing the time jitter of the rotating disk and increasing the blocking success rate.

[0054] 6. The present invention provides a method for generating strong X-rays that can block Z-pinch spatter. The size, shape, and rotation speed of the disk, as well as the installation positions of the disk, laser, and photodetector, can be adjusted according to actual working conditions.

[0060] Figure 5 This is a trigger timing diagram for a second embodiment of the high X-ray radiation source capable of blocking Z-pinch spatter of the present invention.

[0061] The attached figures are labeled as follows:

[0063] like Figures 1 to 3 As shown, a strong X-ray radiation source capable of blocking Z-pinch sputtering includes a delay timer, a counterweight 10, a thickened structure 11, a clamp 7, a mounting bracket 4, a disk 1 mounted on the mounting bracket 4, a motor 3, a photodetector 6, and a light-limiting slit 2, a laser 5, and a Z-pinch load 8 mounted on an external experimental platform.

[0064] The light-limiting slit 2 is vertically positioned on the X-ray path emitted from the Z-pinch load 8; the photodetector 6 is vertically positioned on the laser path emitted from the laser 5; the disk 1 is located between the Z-pinch load 8, the light-limiting slit 2, the laser 5, and the photodetector 6, and the disk 1 is connected to the drive shaft of the motor 3 via a clamp 7; an opening 9 is provided on the disk 1, the size of which is larger than the size of the light-limiting slit 2; for the laser and X-rays to pass through; the input end of the delay timer is electrically connected to the photodetector 6, and the output end is electrically connected to the Z-pinch load 8, for triggering the emission of X-rays from within the Z-pinch load 8.

[0065] In this embodiment, the disk 1 driven by the motor 3 needs to be installed between the Z-pinch load 8 and the light-limiting slit 2 to ensure that the Z-pinch load 8, the opening 9, and the light-limiting slit 2 are in the same collimated optical path. The disk 1 should be positioned as close as possible to the light-limiting slit 2 to obtain sufficient blocking time and improve blocking capability. Furthermore, the outline of the opening 9 is required to be larger than the size of the light-limiting slit 2 to ensure that X-rays can pass through the opening 9 into the slit. The laser 5 and the photodetector 6 are placed on opposite sides of the disk 1, maintaining the same collimated optical path to ensure that the laser can pass through the opening 9 and be received by the photodetector 6. The electrical signal output by the photodetector 6 is used to synchronize the opening time of the light-limiting slit 2 with the X-ray emission time.

[0066] The counterweight 10 is located on both sides of the opening 9 near the center of the disk 1; the thickened structure 11 is located on both sides of the center of the disk 1. The thickened structure 11 matches the clamp 7 to ensure that the contact area between the thickened structure 11 and the clamp 7 is maximized, so that the disk 1 rotates more stably.

[0067] When an opening 9 is designed on the disk 1, the shielding ability and stress are significantly improved. The range of splash velocity that can be blocked by the Z-pinch load 8 is expanded to 55.9 m / s to 10000 m / s, and the maximum stress is reduced to 46.5 MPa.

[0068] Preferably, the thickened structure 11 and the disk 1 can be integrally manufactured for ease of processing; the light-limiting slit 2 is a rectangular structure; the opening 9 is a concave or V-shaped structure, and its opening angle θ is optimally within the range of 1° to 10°, which needs to be confirmed according to specific working conditions. Simulation calculations are used to ensure that the thickening treatment of the disk 1 simultaneously achieves the purpose of balancing the center of mass. It should be noted that when thickening the root of the opening 9, the thickening needs to be performed along the contour of the opening 9, and simulation calculations are used to obtain the optimal solution.

[0069] The working principle of the above embodiments is as follows:

[0070] During operation, motor 3 drives disk 1 to rotate at a constant speed. The dimensions and rotational speed of disk 1 need to be calculated based on the actual working conditions to ensure that opening 9, Z-pinch load 8, and the light-limiting slit 2 of the diagnostic equipment are in the same collimated optical path. This ensures that the X-rays generated by the implosion of Z-pinch load 8 (i.e., Z-pinch load 8) can enter the light-limiting slit 2 through opening 9. In addition, laser 5 and photodetector 6 are respectively installed on both sides of disk 1 and maintain the same collimated optical path.

[0071] When opening 9 is in the collimated optical path of laser 5 and photodetector 6, photodetector 6 receives the laser and outputs a positive electrical signal. Therefore, when disk 1 rotates at a constant speed, photodetector 6 will output a periodic signal that is the same as the opening period T of the light-limiting slit 2 but ahead of it. After the signal is synchronously delayed by a delay timer, it is used as a trigger signal to synchronously trigger the internal burst emission of X-rays from the Z-pinch load 8, ensuring that opening 9 coincides with the light-limiting slit 2 when the X-rays are emitted (i.e., the light-limiting slit 2 is open). Subsequently, after the X-rays enter the light-limiting slit 2, the optical channel (i.e., the light-limiting slit 2) is quickly blocked, preventing subsequent sputtering material from the Z-pinch load 8 from entering the light-limiting slit 2.

[0072] In this process, motor 3 drives disk 1 to rotate, periodically opening the light-limiting slit 2; disk 1 is not required to accelerate in a very short time, nor is a braking system needed, and disk 1 always rotates at a calculated speed; lasers 5 and photodetectors 6 installed on both sides of disk 1 are used to synchronize the opening of the light-limiting slit 2 with the emission of X-rays from the Z-pinch load 8, and the periodic signal output by photodetector 6 is used to actively control the synchronous triggering of X-ray emission, significantly reducing time jitter.

[0073] Meanwhile, the present invention also provides a method for generating strong X-rays that can block Z-pinch spatter, comprising the following steps:

[0074] 1) Prepare the above-mentioned strong X-ray radiation source that can block Z-pinch sputtering material;

[0075] 2) Determine the radius of disk 1 and the angle of opening 9 based on the dimensions of light-limiting slit 2;

[0076] In step 2), the light-limiting slit 2 is a rectangular structure;

[0077] The dimensions of disk 1 are determined based on the light-limiting slit 2 using the following formula:

[0078]

[0079] In the formula: R is the radius of disk 1, θ is the opening angle 9, and r is the width of the light-limiting slit 2. l The length of the light-limiting slit is 2.

[0080] In this embodiment, the length of the light-limiting slit 2 is... l If the value is 5cm, then the radius of the disk 1 and the angle of the opening 9 corresponding to different widths of the light-limiting slit 2 can be determined according to the above formula. For diagnostic equipment that does not install the light-limiting slit 2, the radius of the disk 1 and the angle of the opening 9 can be calculated directly based on the size of the window of the diagnostic equipment (analogous to the size of the light-limiting slit 2).

[0081] 3) Calculate the rotational speed of disk 1;

[0082] Based on the velocity v of the splash from Z-pinch load 8, the distance L from the center of Z-pinch load 8 to the light-limiting slit 2, and the angle of opening 9, the rotational speed n of disk 1 is calculated using the following formula:

[0083]

[0084] The rotation speed required for disks 1 of different sizes to block light-limiting slits 2 at different positions can be determined based on this formula.

[0085] 4) Turn on motor 3 to drive disk 1 to rotate, and at the same time turn on laser 5. After motor 3 has rotated steadily, start Z-pinch load 8 to keep it in pre-trigger state.

[0086] When the opening 9 rotates to a position opposite to the photodetector 6, the photodetector 6 receives the laser signal emitted by the laser 5 and sends a trigger signal to the delay timer.

[0087] When the opening 9 rotates to a position opposite to the light-limiting slit 2, the trigger signal, after being delayed by the delay timer, synchronously triggers the internal burst emission of X-rays from the Z-pinch load 8. The X-rays enter the light-limiting slit 2 through the opening 9, and then the disk 1 blocks the light-limiting slit 2, thus completing the blocking of the splashes from the Z-pinch load 8.

[0088] The method of this invention allows for flexible design of parameters such as the radius, opening angle, and rotation speed of the disk 1 based on the size and position of the light-limiting slit 2 to be blocked, and the disk 1 can be replaced with the corresponding fixture 7. For disks 1 with thickened treatment, attention should be paid to the deformation of disk 1 during processing. 3D printing technology can be used to avoid deformation caused by turning and milling and reduction of stress limit caused by welding.

[0089] Considering the time jitter between the laser signal received by the photodetector 6 and the X-ray emission from the Z-pinch load 8, and the time for the light-limiting slit 2 to receive the X-ray, a certain margin needs to be left on the original opening angle 9 so that the device of the present invention allows for a time jitter of 25%t, where t is the time required for the disk 1 to complete the blocking of the light-limiting slit 2 after the Z-pinch load 8 emits the X-ray.

[0090] Furthermore, the high-speed rotating disk 1 is greatly affected by stress. Therefore, it is necessary to minimize the stress on disk 1 caused by centrifugal force, while avoiding eccentric forces caused by the displacement of the center of mass of disk 1. Therefore, the optimization measures for disk 1 are as follows:

[0091] 1. Thickened structures are provided at the root of opening 9 and on both sides of the center of disk 1. Specifically, thickening treatment can be carried out on both sides or thickening parts can be added. The thickened area at the center of disk 1 needs to match the size of fixture 7. The thickened structure 11 is in the shape of a ring. The thickening treatment at the root of opening 9 needs to be carried out along the outline of opening 9. The thickened part is in the shape of a rectangle with a notch (the notch is at opening 9). When thickening, it is preferable to keep the two sides of disk 1 symmetrically thickened. It is better to thicken each side by 2mm. Simulation calculation shows that this treatment can effectively reduce the maximum stress of disk 1.

[0092] 2. In the case of opening 9 on disk 1, by increasing the counterweight of disk 1, the center of mass is balanced to the center of the circle. This treatment reduces the minimum velocity of the Z-pinch load 8 splash that disk 1 can block by 1 / 2, improves the stability of disk 1 operation, reduces the maximum stress of disk 1 by 45%, and improves the ability to block the Z-pinch load 8 splash.

[0093] 3. For disks 1 of different sizes, the size of the counterweight part is different. Through simulation calculation, the thickening treatment of disk 1 can achieve the purpose of balancing the center of mass.

[0094] Example 2

[0095] like Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that two openings 9 are made on the disk 1, and only the thickened structure 11 is provided.

[0096] like Figure 5As shown, the disk 1 is 850cm away from the Z-pinch load, and the width of the light-limiting slit 2 is 0.1cm. The parameters of the disk 1 are: radius 11cm, symmetrical double-sided openings 9, opening angle of 9 2°, thickness 2mm, and rotation speed 6667rpm. The time required for the disk 1 to complete the blocking is t = 50μs, the allowable time jitter is 12.5μs, the velocity range of the splashes from the Z-pinch load 8 that can be blocked is 112.4m / s to 10000m / s, and the delay time required for the photodetector 6 to output the electrical signal is 2034μs. When the disk 1 is made of aluminum alloy 7075-T6, the maximum stress is 85.2MPa, which fully meets the design requirements.
