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 |

| Tier | Unit |
| Source | insertion-device (confirm: i10 is a soft X-ray twin-APPLE-II beamline; dodal binds the two APPLE-II insertion devices (modelled below) but not their period; the undulator detail is SRC-1) |
Enclosures¶
| Enclosure | Role | Facility | Permit signal |
|---|---|---|---|
i10-optics |

Machine¶
The machine-level source state, observed not driven.
Enclosure: i10-optics.
Note
dodal's Synchrotron device is the observe-only machine state, the loose StorageRing pattern reused from the Diamond siblings (MACHINE-1).

Insertion devices¶
The twin APPLE-II undulators, the variable-polarization soft X-ray source.
Enclosure: i10-optics.
Note
Both APPLE-II undulators bind the catalog InsertionDevice Family, the i06 (PR #378) precedent: the variable-polarization phase rows (RPQ1-4), the jaw phase, the EPICS energy <-> gap polynomial lookup, and the coordinating controller are per-Asset settings and the bound Model, not a new Family. Both are driven sources feeding the two endstations (SRC-1).

Optics¶
The soft X-ray plane-grating monochromator, the collimating and branch-switching mirrors, and the optics slits.
Enclosure: i10-optics.
Note
The PGM binds GratingMonochromator (the SIX / CSX / ESM / i06 precedent); the mirrors bind Mirror; the slits bind Slit.

Beam axes¶
The two driven source quantities a soft X-ray dichroism / scattering run sets: the incident energy and the X-ray polarization.
Enclosure: i10-optics.
Note
Both bind the catalog PseudoAxis Family (the 2-BM / i06 beam-energy precedent). The incident energy decomposes to the PGM and the APPLE-II gap; the polarization decomposes to the APPLE-II phase rows via the controller. The polarization is the second-fleet variable-polarization axis, modelled exactly as i06: the Pol value set is the axis domain and the linear-arbitrary-angle is the continuous realization of the LA value within the same axis, carried rule-less (POL-1).
