R&D Meeting Summary 8/30/22

PARTICIPANTS: Marco B., Carlos, Tanja

DISCUSSION OF ACTION ITEMS FROM LAST TIME

IJCLAB-ORSAY

• Completed testbench measurements of 10 SciGlass blocks (20cm long) produced earlier in late 2021 (5X) and early 2022 (2X) and working on report

• Initial version can be found here Link
• Notes from 8/23 topical meeting discussing results from the measurement Link

• Sent 10 SciGlass blocks (20 cm long) to INFN

• Working on subcontract with JSA

• no delay in research activities expected

INFN

• Received the 10 SciGlass blocks (20cm) and preparing for testbench measurements including SiPM readout

• Discussion about student travel

• two students available to work on SRO with SciGlass blocks
• plan to match their travel with the CLAS collaboration meeting in early November - time at JLab can be used for designing and assembling the prototype and initial SRO tests. Data taking for SRO could be done in Spring 2023

CUA/JLAB

• Initial measurements of 40cm blocks and preparations for prototype test ongoing

• Performed initial transmittance measurements - longitudinal transmittance of 40cm blocks comparable to 2X series of 20cm blocks

• Initial cosmic tests performed for signal validation

• Blocks installed in 12x1 configuration for initial beam checkout

AANL

• TH reports that AANL has been working on subcontract - need to follow up

PROGRESS REPORT AND PROPOSAL

• Material for progress report:

• Test bench measurements from Orsay
• Test bench measurements with SiPM from INFN
• Initial performance with beam

• For a possible FY23 proposal need to consider that the focus is on EIC Project R&D (not generic) and any overlaps with the other Project R&D topics

• Possible focus for FY23: full SciGlass block optimized in calorimeter

• Topics/milestones for a possible FY23 proposal

• Glass block/photosensor interface optimization (matrix and services)
• Measure ratio of different time components of glass
• Compare performance of different glass geometry shapes
• Optimize
• Documentation

• Action items:

• start drafting progress report and FY23 proposal
• continue measurements and documentation

NEXT MEETING: TUESDAY 27 SEPTEMBER AT 1:00PM ET
