  • These PV names and usages are a template for L1S and the BC1 energy beam-based feedback
  • TBD: the The _A, _ADES, _AAVG give the absolute energy gain of an on-crest electron (they will be calibrated by some external means, mostly using the beam); the units of ADES will be MeV
  • Phase _P, _PDES, _PAVG values give the absolute phase of the RF w.r.t. the beam (they are offset-corrected so that 0 means on-crest)

RESOLVED:

  • The local feedback loops will remain on during beam-based feedback and other user / application inputs
  • The Beam-based feedback takes precidence over other applications and user inputs. when Beam-based feedback is on, lother inputs are disabled
  • the L0B_A, L0B_P PVs will be an absolute value, not a delta.
  • Both amplitude and phase will be available as an actuator for the Beam-based feedback for DL1.  Only one of these will be used at a time
