    keyword=Cryo Levels -- Hall C cooldown

    I noticed a serious decline in the heat output of the HPH and paged the target expert. There was also a slight increase in the temperature of the 15 K coolant, so I called MCC.

    Hall C is performing a target cooldown which is resulting in fluctuations in our 15 K flow and supply temperature.

    I have turned down the fans to 10% to reduce the heat load. The target temperarure seems fairly stable
