SLIA beam line design

Summary form only given, as follows. The Spiral Line Induction Accelerator (SLIA) is a multikiloampere compact electron accelerator. It uses linear induction accelerator modules on the straight sections of a racetrack spiral, with strong-focused bends to recirculate the electrons. The strong focusing is provided by stellarator windings on the bends. Stellarator coils are used to provide the strong focusing on the bends. The matching of the electron beam from a diode through a series of accelerator modules and stellarator bends is a major issue in the design of this accelerator. The beam line design for a proof-of-concept SLIA experiment (10 kA, 7 MeV) has been elaborated. The design demonstrates beam matching from element to element in the focusing system, the design of an achromatic bend, and the requirements for avoiding collective instabilities
