Agenda

1. Respin: Paul K & co
   • WAC Notes January 12 2021
   • PK: large completed (just a few runs left). Meeting on Tue to survey of the data (comparing with the prompt). Robert has analyzed some of the runs and we seem to have about 1% less "good data".
   • PK: we'll try to understand how much of the BeamMod data is actually useable for CREX (currently it is still out).
   • CC: we are doing some work to make the analysis a bit easier, and we are documenting it on the haplog
   • CC: we will continue investigating what the best combination of BPMs and coils are going to be used in the analysis.
2. Target degradation study: Weibin Z haplog4430
   • WZ: this analysis tries to determine the effect of target degradation on the Q2 distribution
   • CG: while this study doesn't completely explain the steady radiation increase, it does show that we can make significant changes (up to 100um) to the center of the target thickness and still get the same Q2 distribution. Combine that with the fact that we have a measurement of the Q2 distribution after a target failed we can be fairly certain that this effect won't have any impact on the PREX-2 result
3. Other (all):
   • Beam modulation meetings are back on - initial plots
   • Respin1 data on the ifarm
   • Aggregator summary
   • DJ: Any suggestions or plots that you think should be included in my CREX overview talk at the Hall A Collaboration meeting are welcome. I'll try to circulate a draft early next week.
