Wiens Chiller - Condensation and new setpoint of 22.0 C
Log Number: 4507557Logbook(s): Entry Makers: suleimanBody:
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.

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.
ABIL Tag #9792 added to IHA0I02.
