OVERALL SCHEDULE

• NPS removal starts on 5/20

• Major milestone is the JLab Open House on 6/8 - NPS is to be on the floor for viewing then

• Discussion of survey - there is a disagreement between the two surveys taken

• one option is to resurvey
• however, Steven L, Paulo, and the survey+alignment team were able to show that the disagreement is due to the calorimeter itself
• Action item: Charles will meet with Steven L, Paulo, et al. and post the explanation of the survey discrepancy in the logbook

NPS DECABLING

• Discussion of de-cabling plan: overall plan is to do this in layers starting with LEd and ending with signal cables

• Plan for connectors coming off: might want to label as repair later and repair now

• Will work at the weekend and/or Memorial Day be needed?

• Action item: Coordination meeting with techs (Josh/Alexandre/Jerry) - where want bins, access

• Space constraints limiting number of people working?

• Action item: Identify and procure materials needed (Josh/Bogdan/Alexandre): gloves, cable ties, bags to protect connectors, labels for bundles with broken connectors, etc. - need to prepare in advance of 5/20

• Emergency contingency plan for if not finishing de-cabling, could one disconnect cables and remove the detector for the Open House?

• in principle that is possible, but requires some planning
• difficulty: if just lay the cables on the platform, one changes the order

STORAGE OF NPS COMPONENTS

• Spare parts and tooling currently not in schedule - need to add.

• Action item: What space is needed? (Josh/Julie/Mitch)
• could they go into the cable carrier? - most likely these are tools that are needed short-term
• some tools come from physics storage and may be able to put them back there

• Chiller storage location may depend on how much residual radiation there is

• may go into physics storage or offsite

• Hardware that does not require climate control can go into fabric storage

• Racks in SHMS need to be moved to Hall A (crates are needed there) - cables can stay in principle

• need some help with removing the cables

NEXT MEETING: THURSDAY 9 MAY AT 9AM ET
