Agenda
- Announcements
- TAGM fiber upgrade underway in Tagger Hall - Richard J.
- Beam monitoring issues
- Update on TPOL polarization results from 2016-2017 - Michael D.
- Verifying systematics for energy deposition cuts in TPOL simulation - pending further work
- Systematics studies with 750um converter data, 2018 data
- Update on hadronic asymmetries - Justin, Alexander
- TPOL readout at high rate - Sasha
- Beamline geometry changes in hdds - Richard J
- small geometry overlaps found in TPOL (support rails, target holders, not critical)
- larger overlaps found in PS vacuum chamber, beam pipe (not critical)
- overlap between target assembly and beam pipe (upstream of target, not critical)
- potentially more serious overlaps between BCAL and FDC (not relevant for this meeting)
- corrections to simulation geometry now pending on github
- Priority issues for next 3 months
- evaluation of beam flux systematic error (spectrum, normalization) - Justin, Sasha
- evaluation of polarization systematics (relative, absolute scale) - Michael Richard
- finishing the first round CBSA simulations (requested 9 months ago!) - Richard
- Upcoming activities
- removal/remounting of 5 virgin 50um diamonds
- CLS measurements (next run starting in January, experimental schedule pending)
- reconfiguration of the tagger for CPP - Richard
- Any other business
