Run Coordinator report: winter 2023 w4
From GlueXWiki
Run Coordination report for the week from 02/01-02/08/2023 (Hovanes Egiyan).
The main focus of this week was production running on diamond and amorphous radiators. Due to accelerator-related issues and Hall D Pair Spectrometer magnet power supply failure we only claimed 37.1h of ABU time. BANU time for the last week was 15.2h, PSPEC-related activities were responsible for ~11.3h of these BANU hours. We did not get beam over the weekend due to the overheating of the dipole magnet at the ramp leading to Hall D. We performed a high beam current test during which we reached 950nA beam current.
We have the following issues during the last week:
- Issues with the TAGH HV module
- PSPEC magnet power supply
- DIRC interlock tripping at low humidity
- LH2 target cooling water over-temperature
The following issues that were identified during previous weeks are not fully addressed yet:
- Start counter rotation indicated by the reconstruction software
- Calibrations of AD00C BCM
