Electron linear accelerators are widely used in pressure vessel manufacturing industry, petroleum and petrochemical industry, heavy machinery industry, nuclear power industry, foundry industry, electrical equipment industry and military industry. It plays an important role in the fields of processing, medicine, hygiene, environmental protection, and material handling.
Features
PTMegaL series linear accelerators are composed of X-ray irradiation Source, control system, high-voltage modulation system, safety interlock system, emergency escape protection device, etc., special driving (optional).
By optimizing key components such as Linear accelerator tubes, modulators and X-ray control systems, the reliability of the entire accelerator is improved, its operation and maintenance costs are reduced, and users are provided with the most cost-effective accelerators.
