Controls¶
The control plane the beamline runs on, and the seam CORA's edge conducts over. Control plane: Tango / Sardana.
P22 runs on the PETRA III control system, Tango with Sardana as the scan / motion SCADA layer, the same floor as the other PETRA III beamlines. P22 shares its optics chain with P09: the undulator, DCM, mirrors, phase retarder, and absorber are P09 devices (p09/ addresses, the P09-MONO host), and P22 adds the HAXPS endstation (p22/ addresses). A motion axis is a Tango motor device, the mirrors spk devices, the phase retarder a phaseretarder device. The handles are read from P22's public OnlineXML registry and carried confirm (CTRL-1, SHARED-1). The HAXPES acquisition (the photon-energy / analyzer sweep over the sample) runs as a Sardana macro; that orchestration is the seam CORA's edge would conduct over its ControlPort (CTRL-2).
