Multiphysics Analysis of Normal Conducting RF Cavities for High Intensity Proton Accelerators

M. Hassan[1], I. Gonin[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermi National Accelerator Laboratory, Batavia, IL, USA

Normal conducting cavities are typically used in the front end of proton accelerators to get the beam accelerated to velocities approximately a few tenths of the speed of light, where superconducting cavities can then be used to accelerate the beam to the speed of light. The warm part of ... Read More
