SciGlass/PWO Prototypes Meeting Summary 9/13/22

Back to EEEMCAL Meetings Page

PARTICIPANTS: Hakob, Hamlet, Josh, Yeran, Petr, Tanja, Vladimir

ON-SITE PERSONNEL

• Hakob is on site

• middle October Arthur at JLab

• Josh taking classes, but can come ~1 time per week (Fridays)

• Yeran anticipated to have EAD within the next week - will be on site at JLab then, but needs to complete required trainings and hall walk-through

• Petr is local to JLab area

• Hamlet, Vardan, Tanja are off-site

OVERVIEW OF THE BEAM TESTS PLANNED 1) SciGlass + PMT

2) SciGlass few blocks with SiPM

3) PWO + SiPM readout (Fernando) - Sasha and Vladimir

4) PWO + SiPM readout (Crytur) - CRYTUR

DEADLINES

• Complete characterization of individual blocks by 1 October (Josh, Yeran, Hakob)

• Transmittance measurement (Yeran, Josh) - complete Friday 16th
• Dimensions (Hakob) - complete by Wednesday Sept 21st
• Module assembly (Yeran, Hakob, Josh) - complete (must be ready) by Sept 27th
• Beam test with 12x1 - aim to install by 28th Sept (Yeran, Hakob, Vladimir)

• By Thanksgiving (November 23rd) complete beam test with 3x3 SciGlass array

• Selection of blocks - central block should be the one with the best characteristics
• Assemble blocks (Hakob, Yeran, Josh, Arthur)
• Test with cosmics before going into the hall (Hakob, Yeran, Josh, Arthur) - in aerogel room, dark box
• Install into the hall and QA in hall up to root file - prototype must be ready October 31st
• Coordination with Hall D (Vladimir)
• hit central, in coincidence with hodoscope, measure energy resolution

• Simulations (Petr, Vardan)

• do simulations with optical effects for 1x1, 3x3, 5x5 (Petr, Vardan)
• address issue with GEANT4 on the farm (Petr)
• additional updates to simulation (e.g., changes in emission spectrum, transmission, other characteristics) - Petr/Vardan

• CRYTUR prototype test will likely be in the last week of October

ACTION ITEMS

• Start on the items above working towards the deadlines
• Further develop the details of a test plan for beam test

NEXT MEETING: TUESDAY 27TH AT 10:00AM ET
