The LHe in and PL-neg temps have been building up a ripple over the last 
few days. Curtis cycled HIC142 Friday evening at about 5:00. I just had 
the Main control room operator (Peter) cycle them again. The ripples died 
right out. 
Originally the ripple was 10.8-11.4K on the LHe-in and 8.9-9.2K on the PL-
Neg. They are now steady at 10.7K and 8.9K.
