Status Update Stony Brook Crew

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

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.

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

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 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.

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

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.
