ND-GAr: HPgTPC+ECAL Weekly Meeting

Tuesday 29 Nov 2022, 11:00 → 12:00 US/Central

Appearance Room (WH13SE) and Zoom

11:00 → 11:20 Roundtable Updates

Speakers: Alfons Weber (JG-Uni Mainz & Fermilab), Diego Gonzalez Diaz, Federico Battisti (University of Oxford), Naseem Khan, Tanaz Mohayai (Fermilab)

General:  Will create a poll in the next week or two to search for a meeting time for Jan 2023.

GOAT:

Alan and Tanaz:  GOAT ready to take data at high pressure.  Plan to collect data with Ar/CO2 all in one day, and later with Ar/CH4

 

TOAD: 

Naseem:  ORC granted early last week for vacuum operation (no HV).   to pull vacuum now.  Hope to pull vacuum this week. Clamps for pressure operation likely to be approved soon.  Some issues with network switch in the electronics rack and will try to contact Dell.  This won't affect vacuum operation.   Plan is to move to FTBF during the week of Dec 12th.  Will need another ORC when we get there.  Using DUNE-DAQ.  Getting HDFI files, though still some issues with getting fragments out.  Using v 3.0.0, and want to move to newest version 3.2 once they see data coming out.

Anezka: Things are looking good.  Simulation now generating energy deposits and raw digits.

 

ECAL:   no update

 

Light collection:   Diego: Reassembled TPC at 1 bar with 1% CF4.  Using a double thick-GEM structure.  Using 5 MeV alpha source.  Can see primary and secondary scintillation, and seems consistent with previous measurements. 

Software: Will get an update from Federico in ~2 weeks. 

 

Met in person in the Gold Mine today  (but really should have been in the Disappearance room).  Probably can't use any room next week for an in person meeting due to a DOE review.
