- 2023/02/07
- picoTDC 200$ for 128 channels - 1000 CHF for board
- if high rate and high resolution need waveform sampling : EIC chips NALU, and EICROC, ALTIROC
- Zhiwen : updates on simulation, single pion background
- 2023/01/31
- [DDVCS]
- [DDVCS tasks]
- Zhiwen shows introduction of detector setup
- Sonny - close muons detector could help for pion background - large angle
- Zhiwen - running single pion background
- JP Chen - pion background in large angle muons - how good muons/pion ?
- Alex : check PVDIS setup with muon detector for CLFV
- Ron : 30 m2 500 K$ in hardware straw tubes, Fermilab 2 inch diameter tube, + electronics
- Scintillators more 10 m2 for 300 K$ 800 $ per PMT, scintillator 6 cm thick
- MRPC : 10 m2 4 M$ + electronics - 1 cm strip size -
- 2022/12/13
- Minimum DDVCS setup
- Updates
- Simulation
- Eric and Zhiwen discussing with Discussion with Zhiwen, Eric and Sebastian, to work on simulation
- Marie has files generated that could be also used for cross checks https://solid.jlab.org/wiki/index.php/DEEPGen_event_generator
- update meson part of gen
- need to check the iron
- Pythia background : check with Zhiwen ( Ye Tian can run Pythia ) , should run in DDVCS simulation and look at muons ( look at what was done for other experiments like SIDIS), look at J/Psi for the tail , check with J/Psi proposal
- Yulia got samples and file reader, Yulia is able to run and make histograms, still need to at analysis, early January : maybe go for LOI for this PAC ( could be run group if DDVCS approved )
- preliminary simulation check by Xinzhan, seems to be able to work, Xinzhan can help on proposal, Geant4 simulation for crystals ( 22 MHz / per crystal for 2 cm x 2 cm )
- Ron Gilman interested to contribute to proposal for muon detector
- Simulation
- Updates
- 2022/10/31

- Summary
- Patrick not done yet with plots, will send in the next few days
- Discussion about trigger rates, triggering on the third detectors after two layers of detector seems ok
- Marie : still testing / debugging bad bins
- Mechanical design : Christine has a preliminary design which covers the acceptance using 12 pieces of iron ( 6 out of 8 large iron slabs ) can only have two layers without getting additionnal iron
