Source

The incident beam, produced, conditioned, and defined before the sample. The controllers that drive these devices are on the Controls page. Each device pairs its human name with its control handle, its key specs, and whether it is field replaceable. new marks a device not yet modeled in CORA; confirm marks a value taken from the docs that staff have not yet verified.

Source insertion-device (confirm: P01 is an undulator beamline (2.5-80 keV); the OnlineXML exposes undulator gap/taper virtual motors (gap_a, gap_b, taper_a, taper_b on p01/attributemotor) but no insertion-device period or parameters, carried pending (SRC-1))

Source

The P01 undulator source. The OnlineXML exposes the gap and taper as virtual (attributemotor) axes rather than an insertion-device device server; the period and parameters are not published.

Enclosure: p01-oh1.

Note

Undulator gap / taper virtual motors on p01/attributemotor; which physical insertion device and its period / harmonics is SRC-1.

Oh1 optics

The first optics hutch: the double-crystal monochromator and the two horizontal-deflection mirrors that monochromate and steer the beam, plus the front-end definition slits.

Enclosure: p01-oh1.

Note

Handles read from the OnlineXML (p01/dcmmotor, p01/dcmener, p01/motor/oh1.*). The DCM energy / Bragg pseudo-motors are virtual; crystal cut and the mirror coatings / stripes are OPT-1.

Oh2 optics

The second optics hutch: the secondary defining slits, a diamond beam monitor, and the RIXS pre-optics translation that selects the EH3 spectroscopy branch.

Enclosure: p01-oh2.

Note

Handles read from the OnlineXML (p01/motor/oh2., p01/vmexecutor/slit1_). The diamond monitor and rixs translation roles are OPT-1 / DET-1.
