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 device

The Sector 2 insertion-device source, upstream of the hutches. EAA does not describe the source, so it is carried thin and confirm as a single undulator pending the source table and the post-APS-U configuration.

Note

Modelled as one InsertionDevice Asset. Device type, period, and gap, and whether the front end feeds more than one hutch, are unconfirmed (SRC-1, TOPO-1).

Monochromator

The monochromator that selects the scanning energy, in the upstream optics area. A hard X-ray microprobe runs monochromatic; the device is carried as a double-crystal monochromator pending confirmation, since EAA does not describe the optics.

Note

Presence assumed from the technique (a monochromatic scanning microprobe); crystal, energy range, axes, and the optics-hutch it sits in unconfirmed (MONO-1, TOPO-1).

Focusing optics

The probe-forming optic in the 2-ID-D hutch: a Fresnel zone plate focuses the monochromatic beam to the scanning spot just upstream of the sample. This is the defining optic of the microprobe and the one EAA's autofocus loop drives (the zp_z focus axis).

Enclosure: 2-ID-D.

Note

The zone plate binds the catalog ZonePlate Family (graduated with 32-ID + FXI). Its focus axis (zp_z in EAA) is the actuator CORA's Conductor would drive during autofocus; the order-sorting aperture standard to a zone-plate microprobe is not evidenced and is folded into OPTICS-1, not invented.
