Checking the Wiens chiller this morning. The chiller was in alarm so I added more LCW from the nearby faucet.

Both Wiens show signs of condensation and rust started to spread - see Figures 1-2.

Raised chiller setpoint to 22.0 C from 15.0 C. Both Wiens angles are now set to 23.25 degrees - see Figure 3.

Moving MOPS to emergency power supply drops the associated segment into lock down. The brief loss of power removes the waveguide pressure signal.

Was looking to try to piggy back on RHEL9 reboots today to at least reload the laser controls. This will require a reboot of iocin1. I think the CIS group will be doing laser work so not sure if this would be a good task to do today?

Tony disabled the harp this morning: https://logbooks.jlab.org/entry/4507525
I added an ABIL entry noting that it is disabled

Depending on the beam behavior during upcoming tests, we'll either leave it this way, or if the charging behavior isn't affected by the harp position, we'll return the harp to normal operation at the next opportunity.
