  1. SSR1 Cryomodule Schedule for PXIEFirst Draft Mark Champion October 18, 2011

  2. Assumptions (Champion, Ristori) • PXIE Overall Completion Milestone (Nagaitsev, Oct. 04, 2011) • Oct 2016: Beam through b=0.1 , 0.2 CM at ~15 MeV with nearly final parameters (1 mA cw, 5  mA peak, arbitrary bunch chopping) • VTS and STF throughput limited to ~2 tests / month each for SSR1 cavities. • QC inspection time will require ~2 weeks / cavity. • Visual inspection, dimensional checks, vacuum leak testing, and RF measurements • The first two cavities will receive bulk chemistry at ANL; the remainder may be processed at AES. • Light chemistry, high-pressure rinsing, and assembly to be performed at ANL. • Hydrogen degassing and low-temperature bake to be performed at FNAL. • Jacketing operations on the first cavity will start not sooner than March 2012. • Jacketing of second cavity to start only after successful testing of first jacketed cavity. • Tuners (whatever design) will be available in May 2012 for installation. • Will need to process & test 9 cavities in order to have 8 good cavities for CM.

  3. Comments / Conclusions • This schedule is only a first draft; many details are missing • For example, nothing has been included for solenoids • The critical path will include processing and testing of the cavities. • There appears to be ample time for the cryomodule design and parts procurement. • Initial Projection: CM completion Feb. 28, 2014 • More details to be added in the coming weeks.
