Design Of Superconducting Multi-Spoke Cavities For High Velocity Applications, C. S. Hopper, Jean R. Delayen
Physics Faculty Publications
Superconducting spoke cavities have been designed and tested for particle velocities up to β0 ~ 0.6 and are currently being designed for velocities up to β0 = 1. We present the electromagnetic designs for two-spoke cavities operating at 325 MHz for β0 = 0.82 and β0 = 1.

Multi-Spoke cavities lack the cylindrical symmetry that many other cavity types have, which leads to a more complex Higher Order Mode (HOM) spectrum. In addition, spoke cavities offer a large velocity acceptance which means we must perform a detailed analysis of the particle velocity dependence for each mode's R/Q. We present here a study of the HOM properties of two-spoke cavities designed for high-velocity applications. Frequencies, R/Q and field profiles of HOMs have been calculated and are reported.
