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 undulator source: a downstream and an upstream undulator on the S08ID straight section.

Enclosure: 8-ID-A.

Note

Two InsertionDevice Assets; whether the pair is canted feeding two branches is SRC-1 / TOPO-1.

Optics

The monochromator, the high-heat-load mirrors, and the white-beam and mono slits.

Enclosure: 8-ID-A.

Note

mono is the MN1 monochromator (energy/theta/wavelength); mr1/mr2 are the FMBO mirrors with coarse and piezo fine pitch and benders. A second in-line monochromator (idt_mono) is MONO-2.

Focusing

The compound refractive lens transfocators that focus the coherent beam for XPCS, and the 8-ID-D slits.

Enclosure: 8-ID-D.

Note

rl1 and rl2 are CRL transfocator lens stacks (ten lenses each on 8iddSoft:TRANS), bound to the graduated Transfocator catalog Family (a CRL focusing optic, also used at 4-ID); the lens spec stays open (OPT-3; see model.md).
