A MODULAR CAVITY FOR MUON IONIZATION COOLING R&D

Le résumé fourni par la source

A goal of the Muon Accelerator Program (MAP) is the development of an ionization cooling channel for muon beams. Ionization cooling channel designs call for the operation of high-gradient, normal-conducting RF cavities in multi-Tesla solenoidal magnetic fields. However, strong magnetic fields have been shown in some cases to limit the maximum achievable gradient in RF cavities. This gradient limit is characterized by RF breakdown and damage to the cavity surface. To study this issue, we have developed an experimental program based on a modular pillbox cavity operating at 805 MHz. The modular cavity design allows for the evaluation of different cavity geometries and materials ‐ such as beryllium ‐ which may ameliorate or circumvent RF breakdown triggers. Modular cavity componentsmayfurthermorebe preparedwith differentsurface treatments, suchas high-temperatureannealingor chemical polishing. This poster presents the design and fabrication status of the modular cavity, as well as plans for the experimental program.
