Source¶
The incident beam, produced, conditioned, and defined before the sample. The controllers that drive these devices are on the Controls page. Each device pairs its human name with its control 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.

| Source | insertion-device (confirm: 2-ID elliptically-polarizing undulator (EPU) on SR:C02-ID:G1A{EPU:1}; gap + phase (polarization) axes; whether SIX shares a canted straight with a sibling beamline is TOPO-1, the EPU type/period is SRC-1) |
Insertion devices¶
The elliptically-polarizing undulator source on the SR:C02-ID straight.
Enclosure: 2-ID-A.
Note
One InsertionDevice Asset; the EPU adds a phase (polarization) axis beyond gap, carried as a setting (SRC-1). Whether the straight is canted with a sibling beamline is TOPO-1.

InsertionDevice |
SR:C02-ID:G1A{EPU:1} |
elliptically-polarizing undulator (gap + phase); type and period are SRC-1, the polarization-phase DOF is carried as a setting not a separate Family | new confirm |
Optics¶
The first mirror, the front-end slit, the polarization diagnostic, and the front-end / photon shutters.
Enclosure: 2-ID-A.
Note
M1 is the first horizontal-deflecting mirror; diagon is the soft X-ray polarization diagnostic (DIAG-1).

Monochromator¶
The plane-grating monochromator that selects the soft X-ray energy, and its slits.
Enclosure: 2-ID-B.
Note
pgm is the plane-grating monochromator (PGM): a premirror at a fixed-focus c-value (cff) plus an interchangeable grating (500 / 1200 / 1800 l/mm) set the energy. It binds the catalog GratingMonochromator Family (graduated across SIX + CSX), not the Monochromator Family (which is a crystal/multilayer Bragg DCM): a grating mono has no Bragg crystal and its resolution is set by the exit slit (MONO-1, see model.md).

Refocusing¶
The refocusing mirrors, their slits, and the exit slit that sets the energy resolution.
Enclosure: 2-ID-C.
Note
M3 and M4 are hexapod-mounted refocusing mirrors; extslt is the exit slit, the PGM resolution-defining element (OPT-1, OPT-2).
