Experiment:
No beam study and no RF recovery this week
https://logbooks.jlab.org/entry/3665804 https://logbooks.jlab.org/entry/3666105
- Taking the production runs during the weekend (03/09 and 03/10).
- Taking the SciFi data from run 4721~4724 (https://logbooks.jlab.org/entry/3665700 and https://logbooks.jlab.org/entry/3665708)
- The production (no LHRS NMR) with monitoring LHRS D-G field (-0.37910)(https://logbooks.jlab.org/entry/3666018) from run 4725-4728
- The production (no LHRS NMR and target alarm silent) with monitoring the from run 4729-4759
Hall:
1) escorted access by ARM and John to reset SciFi motion system
2) escorted access by Jack to reboot the LHRS IOC (https://logbooks.jlab.org/entry/3665788)
3) control access planed at 3:00 pm to install the new LHRS NMR IOC portserver/bad wire and Sieliu will restart the target computer. Meanwhile we insert sieve on the left arm to start optics runs after the access.
Issue
- During the Sunday day shift (3/10,10:43-4:30pm), we were working on "No control on LHRS NMR" issue(https://logbooks.jlab.org/entry/3665647 and https://logbooks.jlab.org/entry/3665658). Jack was able to check the issue by going down to the hall (https://logbooks.jlab.org/entry/3665788), and he ended up with a working plan on Monday.
- At 18:54, the target alarm was on (https://logbooks.jlab.org/entry/3665822 and https://logbooks.jlab.org/entry/3665823) and we couldn't read back the target temperature from the four temperature sensors. Target on Call was called, and the issue may need to power cycle the raspberry-pi target computer." If rebooting the raspberry-pi that controls the target
temperature sensors does not bring back their readings we can carry on with the experiment." ---from Silviu. [[1]]
The above 2 issues need a control access to the Hall, and we plan to have Jack/Ethan and Silviu to work on the issue on Monday 3pm.
Plan
- Collect the production run data with both working Right and Left HRS at 40uA.
- Insert sieve on the left arm, and do the optics run for HRS T1=T4=1, others keeps to 0, see the run plan[[2]]
- plans for the down time during production run.
- Left HRS magnet down, then take the right HRS optics run (positron)
- Right HRS magnet down, then take the left HRS optics run
