"Bypassing" Raster-2 Interlock in Hall C Dump Diffuser
Hall C at current ~1.5GeV energy is using one out of two sets of raster coils -- Figure 2 -- to achieve rastering of the beam on target.
Figure 1: Dump diffuser interlocks before any changes. In the ~top-left box under the trip bits are current limits for Puck, Raster 1, and Raster 2. These are the currents at which the interlocks for each device become enabled. The puck can take up to 10uA. If it is inserted and >10uA is sent, the puck bit faults. Raster 1 and 2 are configured to trip Raster fault bits if they are found to be Off and >46uA is sent.
Extremely large fudge factor change when bypassing 2L03
The SL fudge factor changed from 41 to 15 (-26) when 2L03 was bypassed. Keep in mind 2L12 and 2L13 were brought on to compensate, but this large of a change is really uncommon. The change is corresponding to -8 MeV difference or -16 MV/m difference of expected vs pseudo-measured gradient out of 2L03 at Arc2. Not sure if previous conversations about 2L03's gradient calibrations have been fruitful, but this could be affecting our optics quite a bit.

FFB "plan" as written on the MCC physical white board in the Control Room
Please call Ryan B. with questions. I will link this entry in the PD shift plan. I would have done that sooner, if this would have been brought to my attention.
Please read the white board directly; I'm making this elog entry in case somebody erases the white board accidentally.
Spelling it here exactly as I read it from the physical White Board in the control room:
1. Balance 2A energy locks w/Hall C dipole string (Simona's comment: there's a circle around what appears to be a 1. for counting the steps, don't know what that means)
Downtime Incident CLOSED: 2L03 dropped HV
