Description

technical field [0001] The invention relates to the technical field of lightweight accelerator equipment, in particular to a small DC high-voltage power supply for lightweight accelerators. Background technique [0002] The X-band lightweight electron linear accelerator for industrial non-destructive testing is a high-energy ray detection device. Compared with the traditional S-band industrial electron linear accelerator, the X-band accelerator has the characteristics of small size and light weight, and can be applied to complex working conditions, especially In an environment where the detection environment is complex, the working space is limited, the deployment is difficult, and the mechanical assistance equipment cannot be deployed, the lightweight accelerator can be deployed only by manpower. Component protection, lightweight accelerators are mainly suitable for online in-service testing of large petrochemical installations, on-site testing of nuclear power containment ...
