Optimlzation of the linear induction accelerator construction for maximlzing the bremsstrahlung output

The results of experimental and theoretical optimization of the linear induction accelerator (LIA) construction are presented. The major aim of these investigations was to maximize the bremsstrahlung output near the target face. The work was carried out in two stages: 1) modernization of the injector module and 2) focusing of relativistic electron beam (REB) produced at the exit of the accelerating system (AS) in the increasing axial magnetic field. Besides, the methods of diagnostics of angular and energetic parameters of REB based on measurements of radiation dose fields behind the target are described.
