  • 2022/02/22
    • Kishan from data science group showed HGC ML with small uncertainty. work continue to make difference comparison and summarize results.
    • Chao showed the latest status of ATHENA software how it may be used for solid. the solid example repo will be updated and ready for test later https://solid.jlab.org/DocDB/0004/000438/001/SoLID_software_intro_20220222.pdf
    • Ye showed how rod size affect EC energy resolution
  • 2022/01/25
    • we have a good discussion with data science group about ML for HGC PID and some new idea to try.
    • Weizhi studied jpsi luminosity on tracking and the conclusion is that 4 times of the default 1.2e37/cm2/s can still work for the current GEM. To reach 1e38, adding more GEM plane and make segmented strip will help.
    • Xiaochao has a plan to use DJANGOH for internal RC in DIS generator for PVDIS by building a large 3D lookup table. need to work on PVDIS RES LOI/proposal
    • Ye has some preliminary result for PVDIS EC trigger with background
  • 2022/01/19
    • Vlad showed SIDIS_NH3 at 20 and 24GeV without acceptance file would gain more physics if reach more forward angle
    • Zhiwen showed some preliminary ML for HGC PID and will discuss with data science group next week.
  • 2020/09/22
    • Weizhi updated the hadron tracking in SIDIS_He3 which require higher gain for better efficiency. Tracking for both e and hadron will be explored.
    • Ye has preliminary study of EC performance at large angle for longer endcap.
  • 2020/09/15
    • Jinlong summarize VMM3 digitization and tracking results for PVDIS,SIDIS_He3,JPis for efficiency and accuracy. Occupancy will be provided and SIDIS_NH3 will be studied
  • 2020/09/01
    • Vlad updated SIDIS_NH3 trigger using EC only. Next he will add LGC and SPD into trigger
  • 2020/08/04
    • Weizhi updated the PVDIS setup with longer endcap. The FOM can be optimized with GEM 4 and 5 enlarged and EC large angle performance examined.
  • 2020/07/28
    • Jinlong updated the SIDIS_He3 GEM with VMM can reach 90\% efficiency (track found correctly), while PVDIS was shown 80% previously. JPis and SIDIS_NH3 will be worked on
    • Weizhi showed thin Copper shielding before PVDIS GEM1 can reduce some 100k photon which gives large energy deposition in GEM, but it can generate more secondary charge particles and he will work on further optimization. PVDIS with longer endcap is being worked on also
  • 2020/07/14
    • Jinlong showed 20ns Integration vs Two Timeover-threshold
    • Ye Tian showed comparison of eDIS from eicRate and inclusive_e generator, where the latter has higher rate
  • 2020/07/07
    • Jinlong showed VMM has good result with 25ns peaking time for PVDIS
    • Weizhi showed update of PVDIS tracking with segmented strips
  • 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.

    • 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.

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