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 19
Tier	Unit
Source	insertion-device (confirm: i19 is an undulator beamline; dodal binds the undulator (UndulatorInKeV on SR19I-MO-SERVC-01) but not its period; the undulator detail is SRC-1)

Enclosures¶

Enclosure	Role	Facility	Permit signal
`i19-optics`	optics-hutch	`diamond`	confirm: PSS permit leaf not in dodal; the shared optics enclosure, the optics shutter is the dodal InterlockedHutchShutter (PSSInterlock); permit-leaf names are PSS-1
`i19-1`	experiment-hutch	`diamond`	confirm: PSS permit leaf unknown; the EH1 experiment hutch; the active-hutch shared-optics permit is ACCESS-1 (ENC-1, PSS-1)
`i19-2`	experiment-hutch	`diamond`	confirm: PSS permit leaf unknown; the EH2 experiment hutch (the four-circle + serial endstation); the active-hutch shared-optics permit is ACCESS-1 (ENC-1, PSS-1)

Machine¶

The machine-level source state, observed not driven.

Enclosure: i19-optics.

Note

dodal's Synchrotron device is the observe-only machine state, the loose StorageRing pattern reused from the Diamond siblings (MACHINE-1).

Name	Family	PV	Key specs	Replaceable	Status
`StorageRing`	`StorageRing`	confirm: `Diamond storage-ring state (current, fill); observe-only, the exact PVs are MACHINE-1`	Diamond storage-ring state; observe-only (MACHINE-1)		`new` `confirm`

Optics¶

The shared optics line: the undulator, the double-crystal monochromator, the focusing mirrors, the attenuator, the incident-energy axis, and the optics shutter. Both hutches share these; only the active hutch may drive them (ACCESS-1).

Enclosure: i19-optics.

Note

All reuse existing catalog Families. These are SINGLE Assets in the shared optics enclosure; a non-active hutch may read them but not drive them, and the energy move is a coordinated procedure over the monochromator, undulator, and mirrors gated by the active-hutch permit (ACCESS-1). The mirror coating stripe is a hutch-keyed setting on the mirror (OPT-1).

Name	Family	PV	Key specs	Status
`Undulator`	`InsertionDevice`	`SR19I-MO-SERVC-01:`	the undulator (UndulatorInKeV, energy-to-gap lookup); coordinated with the DCM on an energy move; period is SRC-1	`new` `confirm`
`Monochromator`	`Monochromator`	`BL19I-MO-DCM-01:`	double-crystal monochromator (Si stationary crystal + pitch/roll crystal); energy / wavelength / Bragg / offset with d-spacing readback; a non-active hutch reads it read-only (ACCESS-1, MONO-1)	`new` `confirm`
`HorizontalFocusingMirror`	`Mirror`	`BL19I-OP-HFM-01:`	horizontal focusing mirror with a piezo fine-pitch; coating stripe (Si / Rh / Pt by energy band) is a hutch-keyed setting; the piezo write is access-gated (OPT-1, ACCESS-1)	`new` `confirm`
`VerticalFocusingMirror`	`Mirror`	`BL19I-OP-VFM-01:`	vertical focusing mirror with a piezo fine-pitch; coating stripe setting as the HFM (OPT-1)	`new` `confirm`
`Attenuator`	`Filter`	`BL19I-OP-ATTN-04:`	absorber-wedge attenuator (X / Y wedge motors, BL19I-OP-ATTN-04 / -05); reuses Filter (the i03 precedent); the wedge write is access-gated (ATTN-1, ACCESS-1)	`new` `confirm`
`BeamEnergy`	`PseudoAxis`	confirm: `incident-energy virtual axis over the DCM and the undulator (the access-controlled energy composite); the coordinated DCM + undulator + mirror-stripe move is gated by the active-hutch permit; partition rule and range are MONO-1 / ACCESS-1`	incident-energy pseudo-axis over the DCM and undulator (the 2-BM beam-energy pattern); the coordinated cross-Asset move is the access-gated energy procedure (MONO-1, ACCESS-1)	`new` `confirm`
`OpticsShutter`	`Shutter`	`BL19I-PS-SHTR-01:`	the experiment shutter (InterlockedHutchShutter, PSS-interlocked); the per-hutch operate is access-gated, the interlock is an Enclosure permit concern (PSS-1, ACCESS-1)	`new` `confirm`
