The Muon Ionisation Cooling Experiment (MICE) at the Rutherford Appleton Laboratory uses normal conducting copper cavities to re-accelerate a muon beam after it has been retarded by liquid hydrogen absorbers. Each cavity operates at 200MHz and requires 1MW of RF power in a 1ms pulse at a repetition rate of 1Hz. In order to provide this power, a Thales TH116 triode, driven by a Burle 4616 tetrode is used, with each amplifier chain providing ~2.5MW. This power is then split between the 2 cavities.

Cryomodule development (P McIntosh)

 

DICC Cryomodule
 
As part of the 4GLS design process, ASTeC embarked on a collaborative exercise with Stanford and Cornell Universities, the Lawrence Berkeley National Laboratory in the US and FZD-Rossendorf in Germany to develop a superconducting cryomodule for optimised operation on Energy Recovery facilities. The Daresbury Internation Cryomodule Collaboration (DICC) as it is now known, has enabled ASTeC to take responsibility for coordinating the design, development and integration of the various cavity and cryomodule components to ensure improved performance over the existing ALICE cryomodules procured from industry. Fabrication of the various cavity and cryogenic components, including all tooling and fixtures required to perform the system integration, is now well underway and full system assembly is scheduled for late 2009. The new cryomodule will then be installed on ALICE in 2010 and validated with beam.
