Minutes
- Announcements
- Mark has tagged CCDB v1.02. This primarily fixes bugs related to the use of different variations in JANA_CALIB_CONTEXT.
- Tracking
- Naomi put together this document which describes her investigations on correcting for B-field variations. She also redid her studies of radial B-field variation with finer resolution and found a maximum difference of 3 ns at maximum drift time.
- The current time-to-distance tables for the CDC are generated assuming a magnetic field. Simon is being provided with tables corresponding to zero magnetic field. It was noted that the gas mixture in the CDC has a temperature around 296K.
