Controls

The control plane the beamline runs on, and the seam CORA's edge conducts over. Control plane: EPICS (SLS) + eco / slic (SwissFEL).

Cristallina runs the PSI EPICS stack plus the SwissFEL event-driven DAQ. The CTA sequencer and the EVR program the beam-synchronous trigger pattern (and, in the absence of a pump-probe laser device, mediate the pump-probe timing); the sf-daq, bsread streaming, and the slic acquisition suite are software / floor. The live device facts are in-repo slic Python literals; only runtime paths and a couple of server-side services are non-public (ENV-1).
