| Name | Description |
|---|---|
| GDES | Operation Gradient setpoint (MV/m) |
| GACT | Measured gradient from cavity probe (MV/m) |
| GMAX | Maximum allowable gradient (MV/m) |
| GCAL | Gradient calibration scale factor, nominally 1. Multiply by this when calculating raw register value to set, so increasing GCAL increases output. |
| ADES | Operation Amplitude setpoint (MV) |
| AACT | Measured amplitude from cavity probe (MV) |
| AMAX | Maximum allowable amplitude (MV) |
| ACAL | Amplitude calibration scale factor, nominally 1. Multiply by this when calculating raw register value to set, so increasing GCAL increases output. |
| PDES | Operation Phase setpoint (degrees, where 0 is on-crest) |
| PACT | Measured phase from cavity probe (degrees) |
| PREF | a.k.a.gold, phase offset used by LLRF to convert measured phase to one relative to on-crest operation, adjusted by beam phasing (detrees) |
| FDES | Cavity detuning setpoint (Hz) |
| FACT | Detune seen by the resonance system (Hz) |
| Mode | RF mode (off, pulsed, SEL, GDR) |
| RFCTRL | Master enable for an RF cavity (On, Off) \[How to distinguish this from the SSA specific RF enable register?] |
| RFReady | Status of RF controls, (Ready, Not Ready) set to ready when control loops are closed and RF is continuous. Or will we ever run with pulsed RF? |
| Quench | Status showing when a cavity quenches, from interlocks (Normal, Quenched) |
| STAT | Status bits in software (define the bits) |
| HSTA | Hardware status |
| GTRACE | Gradient waveform from the cavity probe, which is used to calculate GACT (MV/m) |
| PTRACE | Phase waveform from the cavity probe, which is used to calculate PACT (degrees) |
| GFWDTRACE | Gradient waveform from SSA output (MV/m) |
| PFWDTRACE | Phase waveform from SSA output (degrees) |
| GREVTRACE | Reverse/reflected SSA output gradient waveform (MV/m) I'm favoring rev over ref because ref sounds to me like "reference" |
| PREVTRACE | Reverse/reflected SSA output phase waveform (degrees) |
| *ERRTRACE | Error waveforms corresponding to waveforms above, captured and put in a separate buffer when a fault is detected (degrees or MV/m) |
| Any of the above in I/Q equivalent of Amplitude/Phase | |
| PwrFwd | Forward power from SSA to cavity |
| PwrRev | Reflected/reverse power from cavity |
| PzWF | Waveforms from tuner piezo motors, useful for finding microphonics. Units TBD. |
| ALEM | LEM computed integrated RF amplitude (MV) per cavity and per cryomodule |
| PLEM | LEM computed phase (deg) |
| EGLEM | LEM computed energy gain (MeV) |
| CHLEM | LEM computed chirp (MeV) |
