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 on the S09ID straight section.

Enclosure: 9-ID-A.

Note

One InsertionDevice Asset; whether a second undulator or a canted pair feeds a branch is SRC-1 / TOPO-1.

Name	Family	PV	Key specs	Replaceable	Status
`Undulator`	`InsertionDevice`	`S09ID:DSID:`	planar undulator (SRC-1)		`new` `confirm`

Optics¶

The monochromator, the high-heat-load mirrors, the white-beam apertures, and the attenuator.

Enclosure: 9-ID-A.

Note

mono is the Kohzu double-crystal monochromator; mr1/mr2 are the FMBO mirrors with coarse pitch, piezo fine pitch, and benders. The diagnostic flag cameras (flag1-3) and the DAMM mask carried only their insertion-motor PVs in the config and are folded into this note pending identification (DIAG-1).

Focusing¶

The compound refractive lens transfocator and the Kirkpatrick-Baez mirror that focus the coherent beam into the CSSI endstation.

Enclosure: 9-ID-D.

Note

crl is a JJ CRL transfocator lens stack (9idPyCRL:CRL9ID), bound to the graduated Transfocator catalog Family (a CRL focusing optic) that 4-ID and 8-ID also use; its lens material and count stay open (OPT-3; see model.md). kb is the KB focusing pair carrying capacitive-sensor bender axes; modelled as one Mirror Asset (OPT-5).

Name	Family	PV	Key specs	Replaceable	Status
`Transfocator`	`Transfocator`	`9idPyCRL:CRL9ID:`	JJ CRL transfocator focusing the coherent beam (crl9id2x); lens material and count are OPT-3		`new` `confirm`

Beam defining¶

The guard slits that define the focused beam entering the CSSI endstation.

Enclosure: 9-ID-D.

Note

Three guard slits (slit3/4/5) on the 9-ID-D soft-IOC optics; the per-blade axis maps are OPT-2.
