  1. Status Update 01-17-2006 Stony Brook Crew

  2. Progress on Glove Box • None to report. • Bids still out. • Have enough $$$ for big one. • Expect no surprises.

  3. Weekly Shots • Concern about becoming complacent about our skills. • Need continual practice to: • Learn all steps. • Better triage for worst immediate needs. • Have whole team practiced on all steps. • More data on QE reproducibility. • New paradigm: • Weekly shot of apparatus onto GEM in hand (one at a time). • Each week more ambitious in replicating full plans.

  4. Week One Shot Goals • Use final hold down plate (done). • Assembly on Laminar table (new filters, ready). • Use Lid-on insertion of Evap box • As opposed to held open above your head. • No longer extreme contaminant risk. • Pump down to water drop. • Local QE (as is) • 3 chicklets

  5. Additional Progress in Prep for Shot 1 • High Vacuum Storage Vessel Pumped Down • Spring-loaded valves cut off rough pump in case of powerdown (failsafe). • 170 l/s turbo runs smoothly. • First Pumped Friday (empty can). • 2 x 10-5 torr (good, not great). • Plan to He leak chase to be sure of all seals being tight. • Only put in precious content when system established good few at least a few days.

  6. Week Two shot Goals (original) • Initially: • Handle in old Glovebox. • Insert into WIS box. • Gain Test. • Lag in feedthroughs • Initially 9 weeks. • New company…2 weeks. • Can still be proper goal for shot3. • Need new goals for Shot2

  7. Week Two Shot Goals (revised) • Lift table insertion. • Needs extreme cleaning before tent. • Needs bagging where cleaning won’t take. • Fully realized railroad: • Rails on lift table. • Rails on transfer table. • Rails in INFN box. • Practice handling through gloves: • Into test box (no feeds). • Out of test box • On to Vacuum storage.
