PARTICIPANTS: Aaron Brown, Alexandre Camsonne, Bogdan Wojtsekhowski, Brad Sawatzky, Carlos Munoz-Camacho, Carlos Yero, Rolf Ent, Gabriel Niculescu, Hamlet Mkrtchyan, Julie Roche, Marie Boer, Steven Lassiter, Vardan Tadevosyan, Vladimir Berdnikov, Tanja Horn, Charles Hyde

SUMMARY NOTES

FRAME (Carlos)

• Discussion of assembly status and temperature control system

• proposed numbering scheme: start with bottom left and go up (view from back of detector)

• Good progress with the assembly

• getting ready to ship towards end of the year

• some issues, e.g. pipe material and flexibility, with cooling identified and resolved

DSG UPDATES (Aaron)

• All cables ordered

• CAEN HV testing

• all channels so far respond as expected

• EPICS screen development ongoing

• Control screens

• numbering should be consistent with the one proposed by Carlos

• Interlock system

• temperature scanning system

MECHANICAL/DESIGN (Steven)

• Making good progress - some of the ordered parts are starting to arrive

• Paulo has been working with Walter about storing location

FAST ELECTRONICS GROUP UPDATE (Brad S.)

• Full update at next meeting by Chris Cuevas

• Cables:

• RG58 cables - vendor started fabrication (2200 cables), should be ready end of year
• All HV equipment should be there

• Work in SHMS hut

• need two racks, one additional rack has to be moved in

• Reflector shaping tool - waiting for update from Vladimir/Josh

• Chiller unit placement - proposal: on beam left of SHMS, length of chiller lines is 8.2m (detector moving back and forth - need flexible lines), needs less shielding this way

• Space for assembly: need sketch for space needed - Brad can make a first draft

NPS SOFTWARE (all)

• shower clustering, recon done by Ho San - standalone

• worked in Hall A framework
• Action: upload shower clustering/recon codes to github, bring in Steve Wood to compile into Hall C ANa, test with some older calorimeter data

• fADC250 analysis still missing, raw waveform (not currently available)

• possible suitable codes have been used for SBS, decoding for fADC250 - could perhaps be recycled - there should be a github with that
• Action: review and make available the fADC decoding

• Performance of software

• NPS has blocks than Hall A - consider developing performance checks

COLLABORATION MEETING (All)

• Focus on discussions (identify missing pieces) rather than formal presentations

• Proposal: two half days (February 1-2, 2021)

HIGH VOLTAGE DIVIDER

• Action: check with Fernando on anode current test plans

NEXT MEETING: THURSDAY 12 NOVEMBER 2020 at 9:00AM ET
