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 |

| Sector | Sector 06 |
| Tier | Unit |
| Source | insertion-device (confirm: i06 is a soft X-ray APPLE-II undulator 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 |
|---|---|---|---|

Machine¶
The machine-level source state, observed not driven.
Enclosure: i06-optics.
Note
dodal's Synchrotron device is the observe-only machine state, the loose StorageRing pattern reused from the Diamond siblings (MACHINE-1).

StorageRing |
StorageRing |
SR-DI-DCCT-01: |
Diamond storage-ring state (ring current SR-DI-DCCT-01, energy / mode CS-CS-MSTAT-01, top-up SR-CS-FILL-01); observe-only (MACHINE-1) | new confirm |
Insertion devices¶
The twin APPLE-II undulators, the variable-polarization soft X-ray source.
Enclosure: i06-optics.
Note
Both APPLE-II undulators bind the catalog InsertionDevice Family, the same source-undulator anatomy as the EPUs at SIX / CSX / ESM. The variable-polarization phase rows, the EPICS energy <-> gap polynomial lookup, and the coordinating controller are per-Asset settings and the bound Model, not a new Family. Only the upstream IDU exposes the driven energy / polarization handles in dodal; the idd / idu asymmetry is POL-2.

UndulatorDownstream |
InsertionDevice |
SR06I-MO-SERVC-01: |
the downstream (IDD) APPLE-II undulator: gap on SR06I-MO-SERVC-01, locked phase rows, the energy <-> gap polynomial on BL06I-OP-IDD-01; period is SRC-1 | new confirm |

Optics¶
The soft X-ray plane-grating monochromator.
Enclosure: i06-optics.
Note
The PGM binds GratingMonochromator, the SIX / CSX / ESM soft X-ray precedent; grating line density and cff are per-Asset settings.

BL06I-OP-PGM-01: |
soft X-ray plane-grating monochromator: energy on ENERGY, the interchangeable grating (150 / 400 / 1200 l/mm) and the fixed-focus cff are per-Asset settings (MONO-1) | new confirm |
Beam axes¶
The two driven source quantities a soft X-ray dichroism run sets: the incident energy and, the fleet-first, the X-ray polarization.
Enclosure: i06-optics.
Note
Both are virtual axes over the source, bound to the catalog PseudoAxis Family (the 2-BM 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 i06 controller. Modelling polarization as a PseudoAxis sibling of energy is how i06 carries the variable-polarization novelty without a new primitive; the polarization partition rule is carried rule-less by default (POL-1).
| Name | Family | PV | Key specs | Replaceable | Status |

BeamEnergy |
PseudoAxis |
confirm: incident-energy virtual axis (70-2200 eV) over the PGM energy and the APPLE-II gap (InsertionDeviceEnergy, Flyable); the partition rule (grating + the energy <-> gap polynomial) is MONO-1 |
