6/30/22 Updates...

ME

• Stands - UITF: Purchase order placed. BNL: ?
• Collimator - Last week Riad provided drawing, found material but does not know if OHFC. Need (2) per this drawing. media:JL0015777_Cu_collimator.pdf What about ID hole???
• Absorbers - Christine provided drawing 6/3, I forgot to act on this! Need (6) per this drawing => media:Absorber - 240 D 001 14_V4.pdf

Analyzing Magnet

• Power supply with ethernet and rack mount option - PR 6/9, PO 6/13, request 6/24 => https://misportal.jlab.org/reqs/pr/viewPr.do?prNum=412686
• Magnet winding around JLab machined cores - PR 5/31, PO 6/2, request 7/15 => https://misportal.jlab.org/reqs/pr/viewPr.do?prNum=412389

Detector

• BGO crystals - Arrived at JLab, stored in cabinet
• PMT status - (4) Hamamatsu tubes w/ magnetic shield, PR 6/1, PO 6/2, due 8/2 or earlier => https://misportal.jlab.org/reqs/pr/viewPr.do?prNum=412467
• PMT base status?
• Detector box status?

DAQ

• PMT-5R ItoV amplifier with remote control - 6/23 CC order placed to Advanced Instruments Corp, delivery date TBD
• Rack- Last week? we discussed a rack layout showing all components + add/list odds/ends still needed UITF cables, connectors, patch panel, lifting bolts?, wheels?, can we finalize/order these
• Rest of DAQ (hardware and software) - how are we looking for UITF readiness ... Like = Aug 1, Should = Sep 1, Must = Oct 1

Documentation

• NIM paper - 6/29 created overleaf folder with Elsevier Article (elsarticle) template, will share after framing outline => https://www.overleaf.com/project/62bc9efe48a3a93aef37be0a
• Portable Compton Polarimeter Manual - Still TBD, ideas how to outline this one? Do in Overleaf too, or is a Sharepoint Word file better for drag/drop, everyone, etc?

Polarimeter Model

• Model development => 6/27 Probir provided magnetic model to Greg. Eric, can you outline how we used magnet model for PEPPo AM in Geant (to assign B-field in air/magnet, P-field in iron core)?
• Greg present simulation results - Jul 14th
