Superconducting electron linear accelerator

The object of the investigation is to develop a 3-5 MeV superconducting electron accelerator. The accelerator includes the following niobium superconducting elements: an accelerating structure, a chopper resonator, and a reference resonator of the master SHF generator. All the superconducting elements are designed for a frequency of 2.8 GHz. The accelerating structure consists of two independently excited resonators in the form of short-circuited sections of a diaphragmatic waveguide. The injector consists of an electron gun and a system for beam chopping and bunching. The cryogenic system ensures the cooling of the accelerating system from 4.2 to 1.85 K, the total consumption of liquid helium being up to 350 l to provide for 8 hr. operation of the accelerator
