GEM @ Stonybrook Meeting
Wednesday December 08, 2021
3:30 pm, ET
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
- Kicking off the Gem work planning at Stonybrook.
Meeting Disgust
- 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.
- Setting latest JLAb DAQ system: CODA, and configure it to be used for calibrating the prototype GEM trackers (Bill)
- Looking at parsing BigBite date to understand the expected performance.
- Simulation to get expected GEM response? (Not a priority right now)
- 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)
- Manufacturing stage:
- Additional equipment needed:
- Cleanroom
- Gas system? CO2 and Helium mixture.
- How good does the mixture have to be? Does the mixture ratio matter?
- X-Ray gun mounted on arms that move in small stepped
