Description

Technical Field

[0001] The utility model relates to the technical field of real-time monitoring, in particular to a real-time monitoring device for particle beams. Background Art

[0002] Particles refer to the smallest component of matter that can exist in a free state. The first particles discovered were atoms, electrons and protons. In 1932, neutrons were discovered, confirming that atoms are composed of electrons, protons and neutrons. Compared with atoms, they are more basic material components, so they are called elementary particles. Since then, more and more such particles have been discovered, with a total of more than several hundred types, and there is a trend of increasing; in addition, some of these particles have not been found to have internal structures in experiments so far, and some particle experiments have shown that they have obvious internal structures. It seems that these particles do not belong to the same level, so the term elementary particles has become history, and they are now collectively referred to as particles. Particles are not specific substances that actually exist like neutrons and protons, but a general name for them, a model concept. A beam is a stream of particles or energy. Thinner beams are also called rays.

[0003] A detector for real-time monitoring of density distribution of wide charged particle beams disclosed in the Chinese utility model patent application publication specification CN 110879409 U includes a plurality of connecting rods, an upstream grounding electrode plate, a downstream grounding electrode plate, and an upstream secondary electron suppression electrode plate, a beam collecting plate, a downstream secondary electron suppression electrode plate, a blocking grounding electrode plate, and a blocking secondary electron suppression electrode plate, all of which include an insulating substrate. The detector for real-time monitoring of density distribution of wide charged particle beams disclosed in the present invention can be applied to related physical experiments such as biological and material modification irradiation experiments, production of biological products, particle radiation breeding, nuclear pore membrane production, and monitoring of density distribution of charged particle beams in industrial production processes, as well as occasions requiring precise control and real-time monitoring of density distribution of beams.

[0004] However, the device does not have a mechanism to amplify the signal, and its anti-interference ability is low, which makes it easy for large errors to occur during the detection process. The device does not have a shielding mechanism, and cannot isolate external electromagnetic interference, cannot ensure the normal operation of indoor electronic and electrical equipment, and cannot use an electromagnetic shielding room (or darkroom) to simulate an ideal electromagnetic environment, resulting in low accuracy of the detection results.
