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	diamond
Sector	Sector 24
Tier	Unit
Source	insertion-device (confirm: i24 is an undulator MX beamline; dodal exposes the Synchrotron source state (modelled below) but not the insertion-device gap as a device, so the undulator detail is SRC-1)

Enclosures

Enclosure	Role	Facility	Permit signal
i24-optics	optics-hutch	diamond	confirm: PSS permit leaf not in source; the hutch shutter is the dodal InterlockedHutchShutter (PSSInterlock), permit-leaf names are PSS-1
i24-experiment	experiment-hutch	diamond	confirm: PSS permit leaf unknown; the serial-crystallography endstation hutch (ENC-1, PSS-1)

Machine

The machine-level source state, observed not driven.

Enclosure: i24-optics.

Note

dodal's Synchrotron device is the observe-only machine state, the loose StorageRing pattern reused from the Diamond siblings (MACHINE-1). The undulator gap is not a dodal device here (SRC-1).

Name	Family	PV	Key specs	Replaceable	Status
Synchrotron	StorageRing	confirm: dodal Synchrotron device (ring current, top-up, machine mode); observe-only, the exact PVs are MACHINE-1	machine source state; observe-only, not photon-path flux (MACHINE-1)		new confirm

Optics

The double-crystal monochromator, the focusing mirrors, the attenuator, and the aperture.

Enclosure: i24-optics.

Note

All reuse existing catalog Families. The DCM selects the incident energy; the focusing mirrors set the beam at the sample; the attenuator reuses the Filter Family (the I03 / i15-1 attenuator precedent).

Name	Family	PV	Key specs	Replaceable	Status
Monochromator	Monochromator	BL24I-MO-DCM-01:	double-crystal monochromator (motion BL24I-MO-DCM-01:, diagnostics BL24I-DI-DCM-01:); crystal cut, d-spacing, energy range are MONO-1		new confirm
FocusingMirrors	Mirror	BL24I-OP-MFM-01:	focusing mirrors with selectable focus mode (dodal FocusMirrorsMode); coatings and the focus-mode set are OPT-1		new confirm
Attenuator	Filter	BL24I-OP-ATTN-01:	filter-based attenuator (two filter-selection enums); reuses the Filter Family, not a new Attenuator kind (ATTN-1)		new confirm
Aperture	Aperture	BL24I-AL-APTR-01:	beam-defining aperture (OPT-2)		new confirm
