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 canted source: two planar undulators in one straight section, angled apart to feed the two experimental branches. The U33 tuning curve is published; exact device types and which undulator feeds which branch are unconfirmed.

Enclosure: 32-ID-A.

Note

Modelled as two InsertionDevice Assets for the canted pair. The downstream and upstream labels follow the published source table; the planar-period and U33 relationship are carried as SRC-1, the branch mapping as TOPO-1.

Front end

The fixed beam-defining mask, front-end window, and white-beam slits that shape and condition the beam before the monochromator.

Enclosure: 32-ID-A.

Note

Mask, Window, and BeamStop are shared catalog Families, as at 2-BM. JJ X-Ray slits are a four-motor compact slit set on a Beckhoff controller (manual_002).

Optics hutch

The Si(111) monochromator and the P4-50 mode shutter that select between white-beam and monochromatic operation. The monochromator serves the monochromatic branch; in white-beam mode it is bypassed.

Enclosure: 32-ID-A.

Note

The white-to-mono switch is a coordinated, safety-interlocked move (the P4-50 mode shutter plus a white-beam stop and combined monochromatic stops, safety_001). Whether CORA models it as a new Capability or as an extension of the existing energy_change vocabulary is an owner decision (see model.md); the world-fact half is MODE-1.

Safety shutters

The personnel-safety shutters between the optics hutch and the experimental hutches, gated by the PSS.

Enclosure: 32-ID-A.

Note

PSS permit signals TBD (PSS-1).
