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 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.

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.
