  • 2020/06/30
    • Weizhi showed update of PVDIS tracking with segmented strips
  • 2020/06/16
    • Weizhi showed PVDIS tracking with segmented strips
  • 2020/06/02
    • Jinlong showed VMM digitization with PVDIS.
    • Weizhi showed update on NH3 tracking
    • Zhiwen showed SIDIS_NH3 sheet of flame change with target and/or solenoid flip
  • 2020/05/26
    • Weizhi showed more SIDIS_NH3 tracking after a bug fix how gemc handle its target transverse field and initial idea of turning some section off for sheet of flame
    • Zhiwen/Vlad showed the attempt in simulation to put a shielding near NH3 target to block sheet of flame. more study is needed
    • We discussed the organization of collaboration meeting in two weeks and how to track various simulation studies.
  • 2020/05/19
    • Weizhi showed more SIDIS_NH3 tracking which has some features needed to be understood
  • 2020/05/12
    • Weizhi showed first attempt SIDIS_NH3 tracking without background, the result looks promising. He will test it with background next.
    • Jinlong summarized the VMM digitization where a lot of information is obtained and he can move on to do the next iteration
    • Zhiwen proposed for ANL group to test DD4hep with SoLID SIDIS_He3 DIS e- trigger rate on EC with its layout [1] and generator [2] and trigger function [3]. We could add light gas Cherenkov in the study if needed
  • 2020/05/05
    • We had a brief discussion about simulation tasks status
  • 2020/04/28
    • Whitney showed the current DD4hep implementation for SoLID, see recording
    • DD4hep for SoLID instruction will be available later
    • the detector definition is made of compiled C++ library and xml file and there is C++ interface for reconstruction and analysis
    • We plan to do some comparison studies between current gemc based simulation and DD4hep when it's ready.
  • 2020/04/21
    • Science Review preparation with high priority was discussed and a list is at [4]
    • talk about DD4hep with SoLID is postponed to next week

  • 2017/09/19
    • pdf Rich's PVDIS GEM digitization is finished. the occupancy is reduced, but it would need to tracking to tell if it's enough.
    • pdfYe Tian showed comparison with PVDIS EC trigger with background between Jin,Rakitha and her result. There are something need to be understand for the background mixing method she use and she will look into it.
    • computer center will start move to new work disk in a few weeks or so. please clean up and backup you data on work disk to tape if needed. This would be safer than just wait for computer center do the move for us. We can also use volatile for 6 month storage to save space on work.
    • computer center haven't figured out something preventing singularity job on farm. Zhiwen will try to find alternative solution if it won't work out soon.

I suspect in reality could be slightly worse. On page 3 is shown the pedestals rms when the common mode is not corrected"
