Review of minutes from the last meeting
We went over the minutes from the July 1st meeting.
- Sasha has finished testing all of the 23 new PMTs. Recall that there is one problematic tube.
- Both of the issues on energy agreement between Monte Carlo and data on the GitHub repositories (one in halld_sim, one in hdgeant4) have been closed.
Run Readiness
Beni showed plots of ADC pedestals, pulse amplitudes, pulse integrals, and time spectra for all TOF channels from a recent cosmic run. The pedestals had already been adjusted by hand to the four problem channels near the nominal 100 counts. There is a clear channel in a board (16 channels) visible both in the pulse integral and timing plots. Sascha Somov plans to replace that ADC today.
