Development Of Spoke Cavities For High Velocity Applications, C. S. Hopper, R. G. Olave, Jean R. Delayen

Physics Faculty Publications

In response to recent interest in alternatives to TM-type cavities for low-frequency, high-velocity applications we have initiated a program for the development of multispoke superconducting cavities. We have completed the electromagnetic design for two-spoke cavities operating at 325, 352, 500, and 700 MHz with a design velocity of β₀ = 0.82 or β₀ = 1. We present the results of the optimization, higher order mode (HOM) analysis, multipacting analysis, and an initial analysis of multipole effects of the fundamental accelerating mode.
