AD & TD collaborate on first cryomodule for new facility

It is perhaps fitting that the New Muon Lab, a long, low concrete affair facing open fields, sits facing the northern edge of Fermilab's property. The hangar-sized building is a busy place these days, home to the laboratory's Superconducting Radio Frequency Test Facility, and bustling with the work that keeps Fermilab pushing the boundary of high-energy particle physics research.
Crews from the laboratory's Accelerator Division and Technical Division recently wrapped up a month-long collaboration at NML on a beamline vacuum system for the facility's first cryomodule, the technology for future particle accelerators such as Project X and the ILC.
Hidden inside a labyrinthine series of concrete walls six feet thick, the hulking, marigold-yellow tube holds eight SRF cavities-the mechanisms that accelerate particle beams to powerful energies. To do the job, those cavities must be scrupulously clean. A simple dust speck can spell disaster.
Jerry Leibfritz, the SRF Test Facility project leader, said that presented a serious challenge for the technicians installing the cavity string vacuum system.
"Every connection-every last nut and bolt-had to be cleaned with a pure-nitrogen air gun until it was particulate free," he said. The laboratory had to build portable clean rooms around the cryomodule. It took five men a full four weeks, regularly working overtime and weekends, to get the vacuum system in place.
