A 3. 4 MeV linear induction accelerator

A 3. 4 MeV linear induction accelerator has been built for use in free electron laser (FEL) research. This machine consists of a 1 MeV injector followed by eight accelerating induction cells. Each accelerating cell adds 300 kV to the electron beam. Eectron beam with the brightness of 2. 0 × 10
