Description

Technical Field

[0001] The utility model relates to the field of electron linear accelerators, in particular to a beam observation and debugging device. Background Art

[0002] Generally, the irradiation process is as follows: through an electron accelerator, electrons obtain higher energy and become high-energy electron beams with electron radiation. The high-energy electron beams form an electron beam scanning line with a width of 1 - 1.5 cm and an adjustable length in the vertical direction of the conveying direction of the beam downline transmission device through beam scanning technology. The articles to be irradiated pass through the scanning line at a constant speed, and the purpose of insect killing, sterilization, and modification is achieved through the interaction between high-energy electrons and substances. It is a new processing technology and process. Beam debugging is a part of the irradiation process. The electron beam is a beam of electrons generated by an electron accelerator. It is necessary to continuously adjust the parameters of the focusing coil of the acceleration tube to make the finally output high-energy electron beam a circular spot with a diameter of 1 - 1.5 cm, that is, to adjust the waveform of the electron beam output.

[0003] At present, to complete the beam debugging stage of an electron linear accelerator, the process is rather cumbersome. The current observation method is a combination of indirect observation and energy point experiment observation. First, a mirror needs to be placed on the transmission line below the scanning box. By adjusting the reflection angle of the mirror surface, the light of the vertically output beam is reflected to the horizontal direction, and then a camera takes a beam image in the horizontal direction in the distance and transmits it to the main control console for beam spot observation. Then, the parameters of the focusing coil of the acceleration tube are adjusted to adjust the beam. However, due to the low accuracy of indirect observation, energy point experiments need to be carried out with glass and glass slides. By repeatedly conducting energy point experiments to test the beam waveform and find the best balance point, the final parameters of the focusing coil are determined. The entire debugging process is not only cumbersome but also has a long time span. Summary of the Utility Model

[0004] The purpose of the utility model is to address the problems in the background art and propose a beam observation and debugging device, which can streamline the beam debugging process and shorten the debugging cycle by directly observing the shape of the beam spot.

[0006] Preferably, the water tank is of a cuboid structure with a hollow interior.

[0007] Preferably, the skylight is a cubic cylindrical structure, the inner four walls of the skylight are stainless steel wall surfaces, and the bottom of the skylight is tempered glass.

[0015] Embodiment 1

[0016] As Figure 1As shown in the figure, a beam current observation and debugging device proposed by the present utility model includes a water tank 1, rollers 2, a mounting frame 4, a mounting platform 5, and a camera 6; the bottom of the water tank 1 has a downwardly convex skylight 3, and this design is to protect the camera 6 to avoid the beam current energy penetrating the water surface and damaging the camera 6 when the water is scarce; several rollers 2 are arranged on both sides of the bottom of the water tank 1; the mounting frame 4 is arranged at the bottom of the water tank 1; the mounting platform 5 is detachably connected to the mounting frame 4. The camera 6 is a high-level camera with adjustable focus and adjustable aperture, so that the observed beam current light spot is more accurate. The camera 6 is arranged on the mounting platform 5 and faces the skylight 3. The skylight 3 is a cube-shaped cylindrical structure, and the inner four walls of the skylight 3 are stainless steel wall surfaces. The bottom of the skylight 3 is tempered glass, and the tempered glass is light-transmitting for easy observation. The skylight 3 and the tempered glass are glued firmly with glass glue to prevent the water tank 1 from leaking water. The camera 6 is communicatively connected with a network transmission line 7, and the network transmission line 7 is a super category seven network cable to isolate high-frequency signal interference.

[0017] The water tank 1 is a cuboid structure with a hollow interior. The water tank 1, the mounting frame 4, and the mounting platform 5 are all made of stainless steel, which is not easy to rust and has a long service life.

[0018] The direct observation principle of this embodiment is as follows: First, install this device under the electron gun scanning box and adjust the position of this device through the rollers 2 to align it with the center of the scanning box; secondly, inject water to a certain height in the water tank 1. At this time, the water tank 1 and the water are equivalent to a capacitor, which can absorb the beam current energy and protect the camera 6; then assemble the mounting platform 5 and the mounting bracket 4 together and adjust the height of the mounting platform 5 according to the debugging needs; then place the camera 6 on the mounting platform 5, connect the camera 6 and the main control console industrial computer with a super category seven network cable 7 to make the communication normal; then align the camera 6 with the center position of the skylight 3 and continuously adjust the parameters of the camera 6 until the shape of the beam current light spot can be directly observed through the camera 6.

[0019] After adjusting the beam current observation and debugging device, the beam current calibration work can be carried out. First, observe the initial shape of the beam current light spot through the camera 6, and then fine-tune the power supply parameters of the focusing coil of the accelerating tube according to the existing shape of the beam current light spot, and repeat this process to make the finally output high-energy beam current light spot a circular spot with a diameter of 1 - 1.5 cm, thereby determining the parameters of the focusing coil of the accelerating tube and completing the beam current debugging.

[0020] This embodiment has a simple structure, changes the traditional indirect observation mode of the beam current light spot, and is upgraded to directly observe through the skylight 3 and the camera 6, reducing the observation difficulty, improving the accuracy of the observation results, and facilitating the debugging of the debugging personnel. This embodiment streamlines the beam current debugging process, no longer needs to repeatedly enter the maze to hit energy points for debugging during the direct observation process, shortens the debugging cycle, saves time costs, and is relatively safer at the same time. The parts cost of this embodiment is low, the structure and function are stable, and it is suitable for production.
