Minutes of Oct 28 2019 ArgonCube2x2 Installation Meeting
· Attendee: Jim, Gary, Angela, Min Jeong, Steve and Ting
· Status of action tasks from last meeting
- The HA for MINOS magnetic coil disassembly needs to be approved
- HA for electronics decommissioning task needs to be drafted
- FY20 budget to neutrino division came out last week. Division managers are talking to DUNE project to sort out support level for both decommissioning and argonCube2x2
- We had initial discussion for securing two electrical technicians for electronics jobs of decommissioning and 2x2 installation. Looks promising.
- Jim confirmed Lab 8 can be used to store scintillator planes. Ting to talk to Rochester group about transportation arrangement
- Angela and Ting will schedule one more lift training class as soon as we know the decommissioning start date
· Water target thickness survey discussion
- Howard's proposal calls to measure the thickness with water in 3 different levels
- Jim estimated we need 3 techs for 1 day of setup, 1 day initial filling and 1 day re-fill for different water level between survey measurements
- total 3 day for 3 tech labors
- Jim also mentioned the shape of target is mostly determined by the water level (load). Creeping effect (shape changes after filling) is minimal
- Same target was used in KTeV as beam window and we had quite a bit experience with the material
- Need to procure four 55 gallon barrels from stock room
- Filling was done before. All tools and procedures were defined
- Survey will take a week: one day for laser tracker setup and stabilization, three days for survey -- three survey measurements at three water level
- total labor 3 crews for 4 days, plus 2 days engineer time for data analysis
- All those actives needs to be approved by neutrino division management.
- Ting to arrange meeting between Steve Brice and spokes
· We will meet again in two weeks
