Paper Abstract

Proper inclusion of self-field effects and careful design has led to development of induction accelerator gap geometries which afford a factor of 5000 or higher improvement in beam brightness over conventional gap designs form multi-kiloampere, multi-MeV electron accelerators. Because of the resulting TEM-like power feed to the accelerator gap region in these designs, the usual low frequency beam breakup instability associa ted with the induction cavity is suppressed. However , this geometry exhibits a significant , high frequency beam breakup problem associated with cavity resonances in the gap region itself. Analysis of this mode and the current status of simulation studies and methods of suppression of this instability are presented.
