Not ready (numerical 0) = Ready criteria not met

WPCONTODES

Push configuration phase value to PDES. To do this, write 1 to PCONTODES

 ACCL:L1B:0210:PCONTODES
R/WCKP

Cavity needs to be phased with respect to beam. Phasing program should set this to 0 when phasing is complete. It is set to 1 automatically when someone accepts a new Phase Reference Line offset.

 ACCL:L1B:0210:CKP

Okay (numerical 0)

Check phase (numerical 2)

 ACCL:L1B:0210:CKPSUM
WGOLD_PDES

'Golds' PDES. It will cause PREF to be updated and leave PDES at zero. How to use:

  1. Find maximum energy by adjusting PDES
  2. Set GOLD_PDES to 1

Doing so will cause:

a. PREF to be set to (PREF-PDES)

b. PDES will then be set to 0

 ACCL:L1B:0210:GOLD_PDES
R/WPREF

Do not set PREF directly. Instead, use GOLD_PDES above.

Phase offset (degrees) used by LLRF to convert measured phase to one relative to on-crest operation, adjusted by (gold) beam phasing. Recommend not setting PREF directly, but using GOLD_PDES (above).

PREF is subtracted from PDES before writing phase to hardware. PREF is added to the raw phase readback from hardware.

 ACCL:L1B:0210:PREF
R/WPTOF

Phase offset (degrees) used to adjust for changes in beam time-of-arrival, 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.
