Source¶
The incident beam, produced, conditioned, and defined before the sample. A walk along the source-stage devices; the sample and detection stages are documented as their own composed-fixture pages, the controllers that drive these devices are on the Controls page, and the supplies they draw on are in Operations. Each device pairs its human name with the EPICS 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.

Insertion devices¶
The two elliptically-polarizing undulators on the canted SR:C23-ID straight, shared with CSX.
Enclosure: 23-ID-A.
Note
Two InsertionDevice Assets (the canted twin-EPU straight, the same EPUs CSX reads on the 23-ID-1 branch); each adds a polarization (phase) axis beyond gap, carried as a setting, and EPU:1 carries the energy-edge lookup-table switching seen in the profile (carried as a setting, SRC-1). Canted-vs-separate-root is TOPO-1 (32-ID precedent: one root).

Optics¶
The front-end mirrors and the front-end shutter.
Enclosure: 23-ID-A.
Note
m1a is the front-end mirror; m1b1 (with a feedback loop) and m1b2 are the sector-A deflecting mirrors that split the canted source toward the branches. Coatings and axis roles are OPT-1.

Monochromator¶
The variable-line-spacing plane-grating monochromator that selects the soft X-ray energy, the branch mirror, the Kirkpatrick-Baez focusing pair, the slits, and the branch shutter.
Enclosure: 23-ID-2.
Note
pgm is the VLS-PGM (200-2200 eV): a premirror (mir_pit / mir_x) plus an interchangeable grating (grt_pit / grt_x) set the energy, and the profile exposes the energy fly-scan (start / stop / velocity). It binds the catalog GratingMonochromator Family (a further consumer after SIX / CSX / ESM / SST; grating line densities and the energy range are MONO-1). m3b is the branch mirror; dm1 is a downstream deflecting mirror; the KB pair (kb_mirror_h / kb_mirror_v) focuses the beam at the endstation; slt1 / slt2 are the branch slits (OPT-1, OPT-2).
