Summary of August 25 - August 31, 2022
- The first part of the week (Wednesday, Thursday, and Friday morning) was used to change the setup configuration from CPP to PrimEx-eta.
- The second part of the week was used for the beam commissioning, CCAL calibration, TAGM calibration, and starting physics production
- The photon beam commissioning went relatively fast as the accelerator was still on during the configuration change. The beam recovery took less than 3 hours. Also, the commissioning was greatly simplified: no ion chamber threshold determination was needed, and no radiation study was done. During the commissioning, we find out that the Active Collimator was not working properly. The inner -Y quadrant was saturating. This was solved by Nick with the support of Richard. Because of that we lost approximately 4 hours of the beam as access to Collimator Cave was needed.
