Yesterday the beam was expected in Hall C during the swing shift. During the beam restoration the SL 2K cold box tripped: https://logbooks.jlab.org/entry/4197355

Once cryo was recovered in the SL the tuner for cavity 7 in 2L24 become inoperable: https://logbooks.jlab.org/entry/4197489 There is an access in the SL right now to address this problem.

On the Hall C side: there were several accesses yesterday during the maintenance day to troubleshoot few NPS calorimeter channels 16-24, 16-26 and 16-16. In the end the cables for 16-24 and 16-26 were replaced. 

We are currently taking advantage of the accelerator down to take some cosmics data with the NPS calorimeter.

Once beam delivery to Hall C is resumed we will check the beam profile, check beam alignment on C-hole and resume production running at KinC_x60_3.

The hall is in controlled access and the hall C techs are in to pump on the spetcrometer vacuum. Steve Lassiter will come in to certify rotation for the 27 deg separation between HMS and the NPS calorimeter.

There will be a RC meeting at 11 am: https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMXdsUT09
Meeting ID: 161 701 5555
