Problems solved by technology

If you want to monitor the fusion device as a whole, you can theoretically use gamma cameras or hard X / gamma-ray detectors to build a huge detection array, but this will greatly increase the construction cost and space, so this method is actually not feasible
At present, in the world, there is no precedent for monitoring the high-energy optical radiation of the fusion device as a whole

Embodiment 1

[0030] (1) Use the γ-coded hole camera array 2 (including multiple γ-coded hole cameras) to be arranged around the fusion device 1 according to certain rules, and connect the trigger cable. "A certain number" refers to the number of γ-coded aperture cameras used that is determined according to actual needs, and the number is greater than or equal to three in the present invention. "Certain rules" means that the gamma-coded hole camera is installed outside the fusion device, does not require a special window, and its viewing angle needs to cover the entire surface of the fusion device. The surface of the entire fusion device includes the surroundings in the horizontal direction and the upper surface or the lower surface in the vertical direction (you can choose one of the two in the vertical direction). Subsequently, each γ-coded aperture camera array 2 is connected to the control system of the fusion device 1 with a trigger cable. If the fusion device 1 starts to discharge, t...

Abstract

The invention discloses a method for monitoring high-energy optical radiation of a fusion device in real time. The method comprises the following steps of: arranging a certain number of gamma coding hole cameras around the fusion device according to a certain rule to monitor the intensity, position and energy of hard X-rays and gamma-rays generated in the whole space of the fusion device in real time, performing three-dimensional reconstruction on monitoring data, and finally, acquiring the overall high-energy optical radiation energy spectrum with space-time resolution of the fusion device. The method is mainly applied to real-time monitoring of high-energy optical radiation of a magnetic confinement fusion device, and has the advantages of low price and small space limitation.

Description

technical field [0001] The invention relates to a method for real-time monitoring of high-energy light radiation of a fusion device, in particular to a method for real-time monitoring of hard X-rays and gamma rays generated by a fusion device by using a gamma-coded hole camera. Background technique [0002] The high-energy light radiation of the fusion device mainly comes from the γ-rays produced by the fusion reaction in the plasma, the hard X-rays produced by the high-energy electrons hitting the first wall, and the γ-rays produced by the activation of neutrons. By monitoring the energy, flux and position of these high-energy optical radiation, researchers can study the transport of plasma in fusion devices, such as studying the type, amount and distribution of plasma core reactions, and when the plasma ruptures. position and the motion of high-energy particles. [0003] For the monitoring of these high-energy optical radiations, conventional diagnostic instruments mainly...
