Accelerator recuperator FEL works in the following energy range:
1st FEL to 12 MeV, 2nd FEL - 20 MeV, 3rd FEL - 40 MeV. The electron beam current is about 10 mA. When the beam is lost on the walls of the vacuum chamber, the dose rate of bremsstrahlung reaches several kilo gray per hour. After recuperation, the beam (1.5 MeV) enters into the copper dump, the contribution to the dose rate...
