GlueX Time-of-Flight Meeting
Tuesday, July 5, 2016
11:00 am EDT
JLab: CEBAF Center, Room F326/327
Agenda
- Announcements
- Review of minutes from the previous meeting
- PMT Gains: The folowing plots show the signal peak amplitude for hits that are matched to tracks
the data are from different runs where we did a beam current scan starting with 40nA and going up to 150nA. At 40nA beam current the peak amplitudes look still reasonable, but already at 80nA a degradation is noticeable which becomes critical at even higher currents(luminosities). The radiator was 50um diamond. - The degradation of the PMTs over the spring run period is illustated with the following plots shoing the RAW ADC Signal amplitudes for an early run (run 10346) and a late run (run 11634 save as above low current 40nA)
- Calibration Status
- NIM paper: svn co https://halldsvn.jlab.org/repos/trunk/publications/GlueXTOF
