Controls

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

I13-1 runs on the Diamond EPICS / ophyd-async control stack, the same floor as the other Diamond beamlines. The device handles above are bound from the DiamondLightSource/dodal i13_1 module (the BL13J coherence-branch endstation), carried confirm pending staff verification (CTRL-1). The shared I13 source and optics are upstream and not yet in the dodal module, so they are deferred (SRC-1, OPT-1). The ptychography acquisition (the raster scan of the piezo stage coupled to the Merlin far-field capture, then the downstream reconstruction) runs through bluesky plans and a reconstruction pipeline; that orchestration is the seam CORA's edge replaces, driving through ophyd-async / EPICS, while the reconstruction is ComputePort work, not a beamline device (TECH-1). The detector file-writing to the Diamond filestore is plumbing CORA observes, not data it owns (see model.md).
