Controls

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

I-TOMCAT runs on the SLS EPICS control stack at the floor ("control of the beamline and experiment is fully implemented in EPICS"), with the BEC (Beamline and Experiment Control, bec-project) microservice scan/orchestration layer over ophyd introduced for SLS 2.0. The TOMCAT EPICS PV prefix scheme is not public and the per-beamline BEC ophyd device manifest lives on the internal gitea.psi.ch, so the device handles above are left empty pending staff verification (CTRL-1). The tomographic acquisition (the rotation trajectories, the camera streaming, the energy moves) runs through BEC; that orchestration is the seam CORA's edge replaces, conducting over EPICS rather than replacing it (the BEC replace-vs-drive-through boundary is SEAM-1). The camera file-writing to the PSI data store and the Ra/SLURM reconstruction pipeline (Fiji Reco Manager) are plumbing CORA observes, not data it owns (see model.md).
