GEM @ Stonybrook Meeting<br>
Wednesday January 05, 2022<br>
3:30 pm, ET<br>
Meeting Zoom link: https://stonybrook.zoom.us/j/96999714444?pwd=NGhNNXFQQzFlRWxGRnh5VHM1YnN0dz09

== Project background ==
# Klaus' slides on the Moller GEM is to be added here for reference. 
# Stonybrook is assigned to construct 12 out of the 28 layers of GEM trackers for the Moller experiment
# Two prototype trackers to be constructed by late 2022. GEM material (three rectangular sheets) will arrive SBU in early March; frames will arrive later

== Agenda ==
# Cleaning progress on the cleaning room
# Clean room delivery and setup
# Other next step items
## Stand-alone simulation. (Contacted Ciprian)
## Parsing the GMn Gem data. (Contacted GMn)
## QCD Server @ SBU updates. 
## Vassu will give a short introduction to Moller physics during the next meeting

== Summary and Next Step ==
# Clean oom delivery and setup
#* Cleanroom delivered, floor cleaning, awaiting outer tent to be set up
## Full Moller simulation: meeting Ciprian at Friday 2pm 
## Parsing the GMn Gem data: waiting on Andrew's further communication. 
## QCD Server @ SBU updates: computer model + UP + backup storage were selected, awaiting final approval
# During next meeting
#* Vassu will give a short introduction to Moller physics .
#* Vassu will give a short introduction on Moller Simulation.
# Obtaining JLab account for Klaus and Prakhar

== Task list ==
# Sub-tasks (required volunteers, or will be assigned):
#* Preparation stage: 
## Clearing out a perimeter in the basement lab (Bill, Vassu, Weibing).
## setting up the cleanroom. (Klaus, Bill and others)
## Setting up the latest JLAb DAQ system: CODA, and configure it to be used for calibrating the prototype GEM trackers (Bill)
## Looking at parsing BigBite data to understand the expected performance.
## Simulation to get expected GEM response? (Not a priority right now)
## Communicate with machine shop to make a stand for hosting the manufactured prototype based on the CAD drawing (Bill)
#* Manufacturing stage:
## Manufacturing/stretching GEM sheet and mount to bracket (with glue) inside the cleanroom (Klaus and Prakhar)  
#* Calibration stage:
## Operating X-ray gun in in grid and mapping out the efficiency and gain in each sector of the GEM response: efficiency, uniformity, gain, etc (Bill & others)
