Abstract :
Mechanical resonances in superconducting accelerator structures and cryo-module components can lead to coupling between mechanical noise and electron beam parameters. We have studied the mechanical resonance spectrum of a 500 MHz 2-cell structure and cryo-module that was designed and built by Siemens for TRW, Inc., and have measured the effect of these vibrational modes on the RF eigenfrequency of the structure. We identify the most dangerous resonances of this system and discuss related design issues
