Yesterday, we were down for the PSS work in the BSY.
We used this time to take LED and cosmic data.
Last night, around 22:50, we got the CW beam and started continuing elastic calibration data.
The beam was good and ran smoothly overnight.
Today, we are planning to complete the elastic calibration data taking and proceed to BCM calibration.
The deadtime and target boiling studies will be performed after that. The run plan will be discussed during today's RC meeting.
Tomorrow, MCC will perform some beam delivery tests from 3:00 -7:00 a.m., and the accelerator maintenance.
During this time hall will be surveyed and will be put in controlled access ~ 9:30 -10 am.
Some planned work during tomorrow's downtime:
Brad Sawatzky will pull an image of the go_cmagnets virtual machine. This may take 1-2 hours. During this time the remote control for the spectrometer motion control will be down.
Brad will coordinate this with the shift workers. Please let Brad and me know if you have any concerns or objections to this.
Heidi and Hall Techs will be working in the hall for some vacuum issues.
Calorimeter Work: Some repair work for some low-amplitude channels. Maybe some fiber replacement if we get the optical fiber delivered by tomorrow morning.
Please let me know if you want to perform any repair or maintenance work inside the hall tomorrow.
Shifts:
We urgently need some Owl shift workers for some upcoming shifts.
Please consider signing up for the open slots (https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=DVCS-NPS-2023).
There will be the usual RC meeting today at 11 a.m. Zoom information is below:
