Description
To carry out experiments on X-ray flash radiography, a high power linear induction accelerator (LIA) was developed at the Budker Institute of Nuclear Physics. This report describes the main systems of the accelerator and its main parameters. The results of modeling the beam dynamics in the injector and linear accelerator are presented. The simulation is compared to the experimental data. An important aspect of the transverse beam dynamics in this type of accelerators is the presence of beam break up instability (BBU), thus, special attention is paid to the methods of mitigation of BBU and results of such mitigation are presented. A prospective area of application of high-current electron beams with high brightness, created in the LIA, is the generation a terahertz radiation flux in frame of the scheme of a free electron laser (FEL). The issue of using a beam from LIA to generate terahertz radiation is discussed, and the required beam parameters to obtain effective radiation generation are specified.
