Analysis and modelling of improved accelerating cavities for the Recirculating Linear Accelerator (RLA)
By recirculating a relativistic electron beam (REB) in phase with a repeating accelerating voltage, it is possible to construct compact, efficient, high voltage gradient, linear induction accelerators (LIA). Concerns about energy spreads due to degradation of our 1.1-MV, 34-ns duration accelerating activity repeating pulse shapes have resulted in our improving the 24-switch trigger system for the ET-2 cavity, and identifying critical factors in the cavity design that affect the pulse shape. We summarize the improvements (completed and proposed) for the existing ET-2 cavity pulsed power and the status of our design analysis and modelling for the new four-pass accelerating cavities that could produce a 20-MeV REB for RLA. 14 refs., 24 figs.
