Minutes

  • Rachel provided an update on various simulation tasks (all on-going), including:
- Solenoid field influence on electron drift (seems acceptable overall);
- GEM simulation to study ion backflow (seems reasonable for Ar:CO2 mix, but a software issue is suspected for He:CH4 mix);
- Lambda decay background in kTDIS (results indicate one may have an handle on those);
- Beam background on detectors ("first glance").
  • Dipangkar presented a drawing of a device to test the target cell: resistance to pressure (up to 2bars), sagging, etc. Most parts have already been ordered.
  • Ed provided an udate on the test stand:
- JLab will get a Common Readout Unit ordered by BNL;
- a rigid design of the Front-End-Cards have been submitted to vendors; one of them offered to produce 5 units for ~$10k (vs ~$15k); at such a price, they consider ordering 2 more.
