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.

SoftUndulator |
InsertionDevice |
SR:C07-ID:G1A{SST1:1} |
EPU60 elliptically-polarizing undulator feeding the soft branch (SST-1; gap SR:C07-ID:G1A{SST1:1-Ax:Gap}-Mtr, phase and polarization mode controls). Soft energy range about 71-2250 eV. From the sst-base energy/soft.py classes (SRC-1). | confirm |

TenderUndulator |
InsertionDevice |
SR:C07-ID:G1A{SST2:1} |
U42 undulator feeding the tender branch (SST-2; gap SR:C07-ID:G1A{SST2:1-Ax:Gap}-Mtr). From the sst-base energy/tender.py classes (SRC-1). | confirm |

FrontEndShutter |
Shutter |
XF:07ID-PPS{Sh:FE} |
Front-end photon shutter; downstream photon shutters gate the branches at XF:07IDA-PPS{PSh:n}. | confirm |
Optics¶
Condition each branch and set its energy: the soft plane-grating monochromator, the tender double-crystal monochromator, the first and per-branch mirrors, and the white-beam and exit slits. PVs verified against the sst-base energy classes and the endstation TOML device manifests.
Enclosure: 7-ID-A.

SoftMonochromator |
GratingMonochromator |
XF:07ID1-OP{Mono:PGM1-Ax: |
Soft-branch plane-grating monochromator (PGM1; grating, mirror-2, grating-X, CFF and VLS controls, energy XF:07ID1-OP{Mono:PGM1-Ax::ENERGY_SP). Reuses GratingMonochromator (graduated across SIX / CSX / ESM); a fourth sighting. Grating set pending (DCM-1). | confirm |

TenderMonochromator |
Monochromator |
XF:07ID6-OP{Mono:DCM1-Ax: |
Tender-branch double-crystal monochromator (DCM1; Bragg, crystal-select, energy XF:07ID6-OP{Mono:DCM1-Ax::ENERGY_SP). Reuses the Monochromator (crystal Bragg) family. Crystal cut and range pending (DCM-1). | confirm |

XF:07IDA-OP{Mir:M1 |
First mirror (M1, a hexapod-mounted plane mirror) in the front optics; reuses the Mirror family. | confirm |

Mirror |
XF:07ID1-OP{Mir:M3ABC |
Soft-branch focusing / steering mirror (M3ABC; M4 / M5 mirrors sit downstream per endstation). Reuses the Mirror family. | confirm |

XF:07IDA-OP{Mir:L1 |
Tender-branch mirror (L1; an L2AB mirror with a wedge sits downstream). Reuses the Mirror family. | confirm |

Slit |
XF:07IDA-OP{Slt:01-Ax: |
Front-end / FOE beam-defining slit. | confirm |

ExitSlit |
Slit |
XF:07ID2-BI{Slt:11-Ax: |
Monochromator exit slit (slitsc) setting the soft-branch resolution. | confirm |

EnergyAxis |
PseudoAxis |
The master energy axis: a coupled pseudopositioner per branch. The soft branch co-moves the EPU60 gap / phase with the PGM (range about 71-2250 eV); the tender branch co-moves the U42 gap with the DCM. The active branch is selected by the endstation in control. Whether energy is scanned as the measurement is the NEXAFS / spectroscopy question (ENERGY-1). | confirm |
