Summary
We did not have beam Thursday Day as the the accelerator was still troubleshooting issues with the BSY PSS controls (https://logbooks.jlab.org/entry/4189049).
We got beam late Swing, followed the beam checkout procedure and proceeded to the third and last elastic setting (https://logbooks.jlab.org/entry/4188925).
When we resumed data taking, it became apparent that there is a dead channel in the NPS calorimeter (https://logbooks.jlab.org/entry/4189069), so it was decided to make a quick access to repair the channel. The repair took longer than expected and wasn't successful, so the problem still persists (https://logbooks.jlab.org/entry/4189167). Our attempts to fix the channel overlapped with the accelerator issues, so the beam was not available for the rest of the Owl shift (https://logbooks.jlab.org/entry/4189087).
Overnight we took about a half of our last elastic setting. Taking into account that we still need to take the rest of the elastic data and that the dead NPS channels have to be repaired, it was decided to reschedule the move of the calorimeter to Monday (https://logbooks.jlab.org/entry/4189173). Today we will fix the NPS channels, then take the rest of the elastic data, and then proceed with the KinC-x50-2 optics data (Sweep Magnet off and on) (less than 2 PAC shifts). We will take additional elastic data as time permits.
Currently the Hall is in Controlled access.
Let's have an RC meeting today at 11 a.m.
Planned Accesses to the Hall
Hall is in Controlled access to repair the dead NPS channels.
