Abstract

In this paper we discuss the justification of a beam recirculation scheme in a prototype model of an accelerator with standing wave, the justification of a calculation method for bending magnets and the choice of their geometry, the calculation of the radial and longitudinal dynamics of particles in a system with beam recirculation, and the influence of various parameters of the scheme on the beam characteristics. In selecting the beam recirculation scheme, the fact is determinative that, in the operation of the linear electron accelerator in the standing wave mode, it becomes possible to perform an acceleration of the beam in the opposite direction in the same structure, which does not lead to a significant increase in the size of the entire setup. It is also reasonable to stay with the double passing of the beam along the biperiodic retarding structure, which greatly simplifies the technological implementation of the recirculation process scheme.
