Technical Field

[0001] This invention belongs to the field of artificially controllable nuclear technology applications, specifically relating to a portable parallel neutron irradiation system and method. Background Technology

[0002] Neutron irradiation technology has wide applications in nuclear science, materials science, agricultural breeding, industrial detection, and medical research. Traditional neutron irradiation experiments typically rely on large neutron generating facilities (such as reactors or accelerators). These devices are bulky, heavy, and extremely energy-intensive, making them difficult to move and deploy, thus limiting their flexibility in laboratory environments and field applications. Furthermore, traditional irradiation systems often employ a single or limited number of irradiation directions, resulting in low irradiation efficiency and difficulty in meeting complex irradiation requirements at multiple angles and locations. In addition, the typically monolithic design of traditional systems leads to difficulties in maintenance and high operating and maintenance costs, which to some extent limits the application scope and efficiency of neutron irradiation technology.

[0003] In recent years, with the development of miniaturized nuclear technology, researchers have begun to explore how to develop neutron irradiation devices towards compactness and high efficiency. However, existing miniaturized neutron source systems typically face problems such as insufficient energy, poor stability, or low irradiation efficiency, making it difficult to meet irradiation requirements in various scenarios. Meanwhile, traditional irradiation systems often require complex operating procedures when simultaneously irradiating multiple target areas, leading to low experimental efficiency. Therefore, developing a miniaturized, low-energy-consumption, highly efficient, and flexible neutron irradiation system is a problem that urgently needs to be solved by those skilled in the art.

This portability allows the system to be flexibly deployed in various scenarios such as laboratories, industrial sites, or field experiments, adapting to different irradiation environment requirements and providing a new solution for laboratory research and industrial applications, enabling efficient and convenient neutron irradiation processes. The specific details of the system of this invention are as follows: A portable parallel neutron irradiation system includes a miniaturized neutron source system and an integrated control terminal, wherein: The miniaturized neutron source system includes a miniaturized pulsed power source A, which serves as the initial driving energy for the neutron source, providing a high-voltage pulse signal (current pulse) to drive the neutron source to undergo a nuclear reaction and generate a high-energy neutron beam for irradiation experiments; a miniaturized neutron source B, used to realize the nuclear reaction and generate a stable high-energy neutron beam for precise irradiation of the experimental object; a mobile base C and a carrier base D, used to mount the miniaturized pulsed power source A and the miniaturized neutron source B, respectively; the mobile base C is equipped with a cable reel, which pulls the carrier base D along a positioning track F pre-laid in the irradiation area at a constant speed via a cable E, achieving uniform irradiation of the experimental object on both sides of the positioning track F; and a monitoring camera G, which can acquire real-time images of the operating area for monitoring the irradiation process and recording the results.

[0020] The integrated control terminal includes an integrated chassis H and a terminal industrial control computer J. The integrated chassis H contains an integrated controller and a DC main power supply. The integrated controller is the hub for various control signals, responsible for various power inputs and outputs, control signal inputs and outputs, and processing, ensuring the normal operation of the system.

The terminal industrial control computer J is responsible for setting and monitoring system parameters (such as irradiation parameters), processing and analyzing data (such as system status and parameters), and realizing communication and interaction with external devices. In addition, the system also includes a portable lifting platform I. The terminal industrial control computer J is installed on the lifting end of the portable lifting platform I, and the integrated chassis H is installed on the lower support platform. The bottom is equipped with universal casters with wheel locks, which facilitates the carrying and movement of the integrated control terminal and the operation of the miniaturized neutron source system.

[0021] During operation, the portable parallel neutron irradiation system involves three main parts in its signal transmission: the main DC power supply outputs three DC power sources and two low-power DC power sources, which power the integrated controller, the terminal industrial control computer J, the take-up and lay-out reel, the miniaturized pulse power source A, and the monitoring camera G, respectively; the terminal industrial control computer J provides one control signal stream to transmit instructions to the integrated controller; the integrated controller provides two control signal streams to transmit instructions to the main DC power supply and the take-up and lay-out reel, respectively; and the miniaturized pulse power source A provides multiple high-voltage pulse signals to drive multiple miniaturized neutron sources B to generate high-energy neutron beams. Based on the above technical solution, the working method of the present invention is as follows: Step 1, System Assembly; Assemble the multi-channel ( Figure 1In the example, a 7-channel positioning track F is placed at the target position in the irradiation area, and experimental objects are arranged around both sides of the positioning track F, i.e., around the path that the miniaturized neutron source B needs to pass through; a miniaturized pulsed power source A is assembled and installed on a mobile base C; a carrier base D is assembled on each positioning track F, and a miniaturized neutron source B is installed on each carrier base D; the miniaturized pulsed power source A is connected to each carrier base D via a cable E using the take-up and release wheel on the mobile base C, and then connected to the miniaturized neutron source B.

[0022] A specific arrangement form such as Figure 1 As shown, multiple positioning tracks F are arranged in parallel, with experimental objects evenly distributed on both sides of each positioning track F. The distance between the experimental objects and the positioning track F is constant. Under the traction of the cable E, the miniaturized neutron source B moves from one end of the adjacent experimental object to the space between them, achieving full radiation. In practical applications, it can be arranged in different forms according to the experimental objects, site environment, etc., and is not limited to this.

[0023] Step 2: The system starts up, and the main DC power supply outputs three DC power channels and two low-power DC power channels to power the integrated controller, the terminal industrial computer J, the take-up and lay-out reel, the miniaturized pulse power source A, and the monitoring camera G, respectively.

[0024] Step 3: Turn on the monitoring camera G to capture and record the irradiation environment and process in real time.

[0025] Step four: The operator sets the irradiation parameters on the terminal industrial control computer J and issues operation commands. The terminal industrial control computer J coordinates all parts of the system to enter standby mode.

[0026] Step 5: The terminal industrial control computer J provides one control signal stream to transmit instructions to the integrated controller; the integrated controller provides two control signal streams to transmit instructions to the DC main power supply and the take-up and release reel, respectively; the miniaturized pulse power source A is started, providing multiple high-voltage electrical signal streams to drive the miniaturized neutron source B to generate a high-energy neutron beam; at the same time, it drives the take-up and release reel to pull the carrier base D along the positioning track F at a constant speed or according to the experimental requirements through the cable E, so as to uniformly irradiate the experimental objects pre-positioned on both sides of the positioning track F in the irradiation area.

[0027] Step six: During the irradiation process, the monitoring camera G monitors the irradiation environment throughout to ensure that the miniaturized neutron source B accurately irradiates the target area; the terminal industrial control computer J monitors the system status and parameters throughout the process, including the movement trajectory of the carrier base D, the neutron beam flux, pulse parameters, etc., to ensure the safety and effectiveness of the irradiation process.

[0028] Step 7: After the preset irradiation time is reached, the DC main power supply stops supplying power to the miniaturized pulse power source A, the miniaturized neutron source B stops emitting neutron beams, and the monitoring camera G confirms that there are no abnormal changes in the irradiation area, and the irradiation process ends.
