Controls

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

12-ID runs on the APS EPICS / ophyd control stack, the same floor as the other APS beamlines. The device handles above are bound from the BCDA-APS usaxs-bits instrument (its src/usaxs/configs/.yml device tables and src/usaxs/devices/.py classes), carried confirm pending staff verification (CTRL-1). The USAXS acquisition (the rocking-curve fly-scan trajectory, the amplifier autoranging, the scaler counting) runs through bluesky plans and the BITS instrument; that orchestration is the seam CORA's edge replaces, driving through ophyd / EPICS, while the area-detector file-writing to the APS filestore is plumbing CORA observes, not data it owns (see model.md).
