Abstract :
The design of the beam line for the Spiral-Line Induction Accelerator (SLIA), a 10-kA recirculating induction electron accelerator that uses stellarator windings to provide strong focusing on the recirculator bends, is described. A SLIA proof-of-concept experiment is in progress, and the design calculations presented are primarily of relevance to that device-a three-bend, two-pass accelerator. Beam matching techniques are described to take the beam from a field-free diode, through the three-turn accelerator, while minimizing beam envelope oscillations and beam centroid excursions. Simulations of the beam dynamics with ABBY, an envelope code for X-Y coupled, linear focusing systems, are displayed.<>
