| Abstract | We describe the analysis and preliminary design of a high-gradient closed-cell 201.25 MHz RF cavity suitable for use in a proof-of-principle muon ionization cooling experiment. The cavities must operate in a strong magnetic field so they must be normal-conducting. They must have a large beam apertures but the shunt impedance can be kept at a reasonable level by closing the beam irises with thin conducting foils or grids of thin-walled tubes. These are almost transparent to the muon beam but present a conducting boundary to the RF fields, maintaining pillbox-like fields on the beam axis. We describe the electrical, mechanical and thermal analysis of the cavities and possible iris structures. The problems of RF heating, breakdown and dark current at high gradient and the integration of the RF with the solenoid cryostat and liquid hydrogen absorbers are considered. A conceptual design aimed at the proposed international Muon Ionization Cooling Experiment (MICE) is presented. |
