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.

Tier	Unit
Source	insertion-device (confirm: two elliptically-polarizing undulators (EPU:1, EPU:2) on the canted SR:C23-ID straight, with a canting magnet / phaser at SR:C23-MG; modelled as one root Unit feeding the 23-ID-1 (CSX) branch (the 32-ID canted precedent), not two roots (TOPO-1); EPU type / period / polarization are SRC-1)

Enclosures¶

Enclosure	Role	Facility	Permit signal
`23-ID-A`	optics-hutch	`nsls2`	confirm: PSS permit leaf not in source; front-end shutter XF:23ID1-PPS{Sh:FE} (PSS-1)
`23-ID-1`	experiment-hutch	`nsls2`	confirm: PSS permit leaf unknown; the 23-ID-1 (CSX) branch; whether branch optics and endstation are separate hutches is ENC-1

Insertion devices¶

The two elliptically-polarizing undulators on the canted SR:C23-ID straight.

Enclosure: 23-ID-A.

Note

Two InsertionDevice Assets (the canted twin-EPU straight); each adds a polarization (phase) axis beyond gap, carried as a setting (SRC-1). Canted-vs-separate-root is TOPO-1 (32-ID precedent: one root).

Name	Family	PV	Key specs	Replaceable	Status
`Undulator_1`	`InsertionDevice`	`SR:C23-ID:G1A{EPU:1`	first EPU (epu1, XF:23ID-ID{EPU:1); gap + polarization phase (SRC-1)		`new` `confirm`

Optics¶

The front-end hexapod mirror and the front-end shutter.

Enclosure: 23-ID-A.

Note

m1a is the FMB hexapod-mounted front-end mirror; coatings and axis roles are OPT-1.

`Mirror_1`	`Mirror`	`XF:23IDA-OP:1{Mir:1`	FMB hexapod-mounted front-end mirror M1A (OPT-1)		`new` `confirm`
`FrontEndShutter`	`Shutter`	`XF:23ID1-PPS{Sh:FE}`	front-end photon shutter, PPS-gated		`new` `confirm`

Monochromator¶

The variable-line-spacing plane-grating monochromator that selects the soft X-ray energy, the refocusing mirror, and the slits.

Enclosure: 23-ID-1.

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. It binds the catalog GratingMonochromator Family, which graduates in this PR: CSX is the second soft X-ray PGM beamline after SIX, earning the rule-of-three (MONO-1, see model.md). m3a is the branch refocusing mirror; slt1/2/3 are the branch slits.
