RC Report - 02/19/2024
--------------------------------

----------------------------
Weekend (02.17/18)
----------------------------
=>  This past weekend was pretty busy. Thank you all who worked on this. The issues with the PMT/bases were fixed; columns 20-23 were uninstalled, PMT/bases were disassembled and reassembled and columns were installed back. All channels operational after refurbishment of columns 20 to 23 https://logbooks.jlab.org/entry/4253570

=>  We asked MCC for a beam ON at 10am but due to some MCC magnet issue we had some delay: https://logbooks.jlab.org/entry/4253547 we got beam back at noon.

=>  We run elastic until 6pm. 

=>  Some issue with the SHMS angles; SHMS angle encoder on magnets GUI and actual angle on the TVs are disagreeing. Steve Lassiter fixed the issue.

=>  Escorted access to the hall to move NPS to 4.0m. Ellen unlocked the magnets.  https://logbooks.jlab.org/entry/4253681

=>  Another issue with HMS rotation. Drive controller status was red. Steve Lassiter wasn't able to reset the HMS/SHMS rotation remotely so we called Ellen again to reset the shunt trip breaker in the hall. (requested an escort)

=>  MCC issue with one of the cryomodules so we went to power cycle the NPS crates  and switched to taking LED data.

=>  About midnight went back to production.

----------------------
Monday (02.19)
----------------------
=> During the Monday Owl Rebooted all NPS crates https://logbooks.jlab.org/entry/4253836 

=> production run....ongoing

 
-------------------------------------------------------
Some planned works on Tuesday (02.20)
-------------------------------------------------------
Beam => MCC is currently planning to stop beam delivery at 7am. The issue is with 2L09, it went down, HV went down on that supply. https://logbooks.jlab.org/search/site/4253236 Estimating time for beam delivery id in the end of the Day shift (not sure).  PD report - https://logbooks.jlab.org/entry/4253911

Work in the Hall => Request from Instrumentation Group to access the BPM IPM3H07A  (Nate Rider+ 3 person) at 10am.  Asked RadCon for full survey at 9am. 

If need an access to Hall C on Tuesday, please coordinate with the RC.
