SoLID Study

Introduction

A collection of studies often involve more than one subsystems

most of codes are at https://jlabsvn.jlab.org/svnroot/solid/study/

timeline and milestone

2018/02 -

• Before science review
  • high priority
    • SIDIS He3 trigger rates in coherent analysis with validated hadron generator
    • Comparison of MARATHON data to hadron generator (halld based), G4
    • Provide ability to reevaluate of all subsystems including sector number (subsystems must be done by respective groups)
    • Jpsi and TCS trigger study, 2 or 3 particle trigger? (Zhiwen)
    • SIDIS NH3 trigger study, what level of rate we have? (Chao, Zhiwen)
    • hadron generator, check halld based generator rate with nuclei target
• After science review:
  • Medium priority
    • DAQ simulation
    • Complete MRPC, SPD studies
    • GEMC implementation of plugins for EC ???
    • GEM position optimization for SIDIS, detailed layout and dead area
  • Low priority
    • Reevaluate radiation in new magnet
    • Migrate to github
    • Expand digitization for all systems, experiment with pseudoanalysis framework
    • Consistency of pion generators for SIDIS window
    • Internal radiative corrections for DIS
    • Reconcile eicRate vs. Yuxiang electron generator
    • initial art implementation
    • Implementation of new magnetic field and subsystem (especially LGC and HGC)
    • first pass at reevaluation of FOM with updated map, detector geometry, critical to make sure there are no major changes in physics reach
