Controls

The control plane the beamline runs on, and the seam CORA's edge conducts over. Control plane: EPICS / bluesky.

ISS scans run as trajectory fly-scans: the HHM energy axis follows a look-up table on a Delta-Tau motion controller while the ion-chamber and fluorescence detectors stream against an encoder. The analog pizza box provides the synchronized multi-channel readout. Controller box models / firmware / IPs are not fully in the profile collection (DRIVE-1).

Name Family PV Key specs Replaceable Status
TrajectoryMotionController MotionController XF:08IDA-OP{MC:06} The Delta-Tau motion controller running the HHM energy trajectory (LUT load / transfer, prepare / start / stop trajectory, progress); a second controller (the XF:08IDB-OP{MC:3-Ax:} axes) drives the von Hamos spectrometer. Standard EPICS motor records drive the remaining axes. Box model / firmware pending (DRIVE-1). confirm
AnalogPizzaBox TimingController XF:08IDB-CT{PBA:1}: The analog pizza box (APB): an eight-channel synchronized ADC (XF:08IDB-CT{PBA:1}: streaming the ion-chamber voltages) plus a trigger / pulse generator (apb_trigger) that times the detectors against the encoder pizza box (XF:08IDA-CT{Enc09:1}) during the fly-scan. Reuses the TimingController family. confirm
