keyword=Target put "to sleep"
In preparation for the 24 hour downtime, I moved to the empty target,
and reduced the coolant consumption of Loop 2 (LD2) by closing the JT
valve down a bit and lowering the fan speed.
Original settings: JT valve ~44, Fan 60 Hz (25%)
Current settings: JT valve ~20, Fan 29 Hz (10%), HPH around 100 W.
Hall C is attempting a cool-down of their target today, hopefully finishing by noon. Because this is the first time there have been a pair of 15 K targets cold in a while, they wanted to make sure we were paying attention...
