  1. Proton source shutdown schedule Mary Convery 12/14/11

  2. General shutdown info • Still not known whether shutdown starts in March or May (or ?) • Duration driven by ANU work in MI – at least 9 months

  3. Shutdown scheduling (Linac) • NTF can only be off for ~2 months • When RFQ is ready (currently on track for May) • If shutdown starts in May, will disassemble I- while still running • All RFQ and Linac tunnel work will take place while NTF off • 2 mech support vacuum crews (split Ben’s crew) • Biggest Linac job is momentum dump sleeve • Mech support work in Booster will be limited during that time (try to keep BRF cavity refurbishment going) • Linac gallery work will continue on NTF off days • Figured ~6 months of Linac gallery work (most while NTF on)

  4. Shutdown scheduling (Booster) • Then ~6 weeks for Booster girder moves for aperture (run beam between moves) • Will be chances for continuing Booster RF and some Linac work during this time • Then ~6 weeks for commissioning • Penciled in RF cavity swaps for tuner refurbishment roughly every 25 days • Only real difficulty scheduling will be during RFQ installation • Solid state work can take place basically at its own pace • Still understanding scope of LCW work • Test stand for cavities may be affected by MI LCW work
