Log Number: 4517430Logbook(s): Entry Makers: alexsBody:
A little after 1500, the MO drive line temperature at 1L12 started dropping, leveling out about 20 degrees C lower. This seems to coincide with a loss of energy throughout the North Linac, as 1L19 also started creeping up until the zone started hitting its drive high. The gang phase of the zone shifted about 4 degrees, but only accounts for a small amount of the 7 MV/m increase 1L19.
