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.

| Property | Value |
|---|---|
| Facility | nsls2 |
| Sector | Sector 8 |
| Tier | Unit |
| Source | insertion-device (confirm: 8-ID in-vacuum undulator on the NSLS-II 3 GeV ring (SR:OPS-BI{DCCT:1} reads the ring current). The profile collection drives photon energy through the HHM trajectory and does not expose the undulator gap / period PVs, so the source identity and range are inferred (SRC-1).) |
Enclosures¶
| Enclosure | Role | Facility | Permit signal |
|---|---|---|---|
8-ID-A |
optics-hutch | nsls2 |
confirm: PSS search-and-secure permit leaf not in source; the front-end shutter is XF:08ID-PPS{Sh:FE} and the photon shutter is XF:08IDA-PPS{PSh} (PSS-1) |
8-ID-B |
experiment-hutch | nsls2 |
confirm: PSS permit leaf unknown; 8-ID-B (PV zone XF:08IDB) is the experiment enclosure carrying the sample stages, ion chambers, detectors, and emission spectrometers (PSS-1) |
Source¶
The 8-ID insertion-device source, the front-end beam-defining slit, and the front-end and photon shutters.
Enclosure: 8-ID-A.

Undulator |
InsertionDevice |
confirm: 8-ID in-vacuum undulator; energy is driven through the HHM trajectory and the undulator gap PV is not in the profile collection (SRC-1) The hard-X-ray insertion device feeding 8-ID on the NSLS-II 3 GeV ring (ring current SR:OPS-BI{DCCT:1}I:Real-I). Period, gap range, and the gap-tracking coupling to the monochromator are not in source (SRC-1). |

Photon shutter gating the beam into the optics enclosure (a two-button open / close shutter). | confirm |
Optics¶
Condition the beam and set its energy: the high-heat-load trajectory monochromator (HHM) and the high-resolution monochromator (HRM), the collimating and focusing mirrors, the harmonic-rejection mirror, the filter box, and the hutch slits. PVs verified against the iss-profile-collection startup files.
Enclosure: 8-ID-A.
| Name | Family | PV | Key specs | Replaceable | Status |

HighHeatLoadMonochromator |
Monochromator |
XF:08IDA-OP{Mono:HHM-Ax: |
The primary double-crystal monochromator (HHM; pitch / roll / theta / Y crystal axes XF:08IDA-OP{Mono:HHM-Ax:P/R/Th/Y}Mtr, and a flying energy axis XF:08IDA-OP{Mono:HHM-Ax:E}Mtr). Energy is swept as a trajectory fly-scan: the Bragg angle follows a pre-computed look-up table on the Delta-Tau controller (XF:08IDA-OP{MC:06}, with per-element Traj:1-9 element / edge / E0 descriptors). Reuses the Monochromator family. Crystal cut and energy range pending (DCM-1). | confirm |

Monochromator |
XF:08IDA-OP{Mono:HRM-Ax: |
The high-resolution monochromator (HRM; theta / Y / pitch axes XF:08IDA-OP{Mono:HRM-Ax:Th/Y/P}Mtr) used for high-energy-resolution incident-beam conditioning. Reuses the Monochromator family. Crystal cut and reflection pending (DCM-1). | confirm |
