W  GOLD_PDES  'Golds' PDES. It will cause PREF to be updated and leave PDES at zero. How to use:  Find maximum energy by adjusting PDES
 Set GOLD_PDES to 1
Doing so will cause: a. PREF to be set to (PREFPDES) b. PDES will then be set to 0  ACCL:L1B:0210:GOLD_PDES 

R/W  PREF  Do not set PREF directly. Instead, use GOLD_PDES above. Phase offset (degrees) used by LLRF to convert measured phase to one relative to oncrest operation, adjusted by (gold) beam phasing.

ACCL:L1B:0210:PREF 

R/W  PTOF  Phase offset (degrees) used to adjust for changes in beam timeofarrival, in particular for changes in bunch compressor path length. Unlike PREF, changing PTOF will immediately change the cavity phase. PTOF is subtracted from PDES before writing phase to hardware. PTOF is added to the raw phase readback from hardware.

R/W  CAV:FUDGE  Beambased scale factor applied to cavity probe amplitude readback. Nominal value of 1. CAV:SCALE = cavity_preliminary_scaling * CAV:FUDGE CAV:SCALE is applied at the waveform level and so FUDGE is included in scalars like AACT, CAV:AMEAN, CAV:AMIN, CAV:AMAX, etc. and waveforms like CAV:IWF, CAV:QWF, CAV:AWF, etc. Example: Cavity ADES and AACTMEAN are 10 MV, but measured energy gain is 11 MV. Set CAV:FUDGE to 1.1. This will cause the RF drive level to be adjusted by 1/1.1 new_drive = original_drive / 1.1 and the cavity amplitude readback to be adjusted by 1.1.  ACCL:L1B:0210:CAV:FUDGE
