Studies of high order modes in asymmetric dual-axis cavity

Abstract:

Electron-beam current in superconducting radiofrequency energy recovery linear accelerators (SCRF ERLs) is limited by beam break-up (BBU) instabilities disrupting beam transport and energy recuperation. The instabilities originate from the accumulation of high order modes (HOMs) in the cavity and positive feedback between the beam and HOMs which is especially evident in multi-pass ERLs. Overcoming the beam current limitations due to BBU instabilities is one of the challenges in accelerator sc...
