Buncher Gradient adjustment
Log Number: 4518159Logbook(s): Entry Makers: samariBody:
minimized the 5S01 IDX dose by increasing the buncher strength from 4.4 to 5 around 00:30. It quieted the 7S01 and 3C12 BLMs with minimal negative effects. The only slight difference is an increase in ILM0L04. Harp swipes showed it didn't effect the longitudinal profile. Transmission through A3 and A4 was alo unaffected
