We continued to take smooth production data after the fan direction was corrected (https://logbooks.jlab.org/entry/4298690, https://logbooks.jlab.org/entry/4298720). During a short escorted access this morning, Dave Meekins increased the pressure in the LH2 target from 35psia to 40 psia. Heidi also checked the JT8 valve during this short escorted access (https://logbooks.jlab.org/entry/4298740). Mark Mathison and Peter Bosted posted comparison plots of LH2/LD2 for various run conditions (https://logbooks.jlab.org/entry/4299368, https://logbooks.jlab.org/entry/4298838). The plan is to take a run on LH2 at 40 psia and move onto positron running and DIS calibrations before the pass change on Thursday. The hall will be swept tomorrow and a number of groups to check on JT8 valve, air conditioning, venting and sensor systems. Let's have an RC meeting at 11:00 am today to discuss more.
