Abstract
We describe the progress on the design of the RF coupling
coil (RFCC) module for the international Muon Ionization Cooling Experiment
(MICE) at Rutherford Appleton Laboratory (RAL) in the UK. The MICE cooling channel design consists of two SFOFO cells
that is similar to that of the US Study-II of a neutrino factory. The MICE RFCC module
comprises a superconducting solenoid, mounted around four normal conducting
201.25-MHz RF cavities. Each cavity has a pair of thin curved beryllium windows
to close the conventional open beam irises, so thatnecessitating separate power
feeds for each of the four cavities has to be separately powered. The coil
package that surrounds the RF cavities sits is mounted on a vacuum vessel. The
RF vacuum is shared between the cavities and the vacuum vessel around the
cavities such that. Therefore there is no differential pressure on the thin
beryllium windows. This paper discusses the design progress of the RFCC module,
the fabrication progress of a prototype 201.25-MHz cavity, and the
superconducting coupling coil that will be cooled using a single, small 4 K
cooler.
