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	nsls2
Sector	11-BM
Tier	Unit
Source	bending-magnet (confirm: 11-BM is a bending-magnet (or three-pole-wiggler) source; the profile collection does not expose the source as a device, so the source detail is SRC-1)

Enclosures¶

Enclosure	Role	Facility	Permit signal
`cms-optics`	optics-hutch	`nsls2`	confirm: PSS permit leaf not in the profile collection; the first optics enclosure (XF:11BMA), hutch grouping is ENC-1 (PSS-1)
`cms-endstation`	experiment-hutch	`nsls2`	confirm: PSS permit leaf unknown; the scattering / reflectivity endstation (XF:11BMB), ENC-1 (PSS-1)

Machine¶

The machine-level source state, observed not driven.

Enclosure: cms-optics.

Note

Observe-only NSLS-II machine state, the loose StorageRing pattern reused from the NSLS-II siblings. 11-BM is a bending-magnet source, not an insertion device, so no InsertionDevice Asset (SRC-1, MACHINE-1).

Name	Family	PV	Key specs	Replaceable	Status
`StorageRing`	`StorageRing`	confirm: `NSLS-II storage-ring state (current, fill, status); observe-only, the exact PVs are MACHINE-1`	NSLS-II storage-ring state; observe-only; the 11-BM bending-magnet source detail is SRC-1 (MACHINE-1)		`new` `confirm`

Optics¶

The double-multilayer monochromator, the focusing mirrors, the FOE slit and attenuator, and the incident-energy axis.

Enclosure: cms-optics.

Note

The DMM binds Monochromator (the 2-BM double-multilayer precedent, a multilayer Bragg optic, not the soft X-ray GratingMonochromator). The mirrors bind Mirror, the slit binds Slit, the attenuator foils bind Filter, and the incident energy is a PseudoAxis over the DMM Bragg angle.

Name	Family	PV	Key specs	Status
`Monochromator`	`Monochromator`	`XF:11BMA-OP{Mono:DMM-Ax:Bragg}Mtr`	double-multilayer monochromator (DMM): Bragg angle sets the energy, with second-multilayer pitch / roll / offset (P2 / R2 / Y2) alignment sub-axes; the d-spacing and energy range are MONO-1	`new` `confirm`
`ToroidalMirror`	`Mirror`	`XF:11BMA-OP{Mir:Tor-Ax:UB}Mtr`	FOE toroidal focusing mirror (X / Y alignment plus the UB bender setting the curvature); coating and bend are OPT-1	`new` `confirm`
`EllipticalMirror`	`Mirror`	`XF:11BM1-OP{MDrive:1}Mtr`	the newer 1D elliptical focusing mirror on its MDrive controller (pitch / x / z); coating is OPT-1	`new` `confirm`
`FoeSlit`	`Slit`	`XF:11BMA-OP{Slt:0-Ax:XGap}Mtr`	the FOE four-blade defining slit (T / B / O / I with virtual center / gap); blade-axis map is OPT-2	`new` `confirm`
`AttenuatorFoils`	`Filter`	`XF:11BMB-OP{Fltr:1}Pos-Sts`	the eight pneumatic absorber foils (Fltr:1-8, in / out) that set transmission, important for the high dynamic range of reflectivity; the foil set is ATTN-1	`new` `confirm`
`BeamEnergy`	`PseudoAxis`	confirm: `incident-energy virtual axis (calibrations near 13.5 keV) over the DMM Bragg angle (lambda = 2 d sin(Bragg)); the partition rule and d-spacing are MONO-1`	incident-energy pseudo-axis over the DMM (the 2-BM beam-energy pattern); MONO-1	`new` `confirm`
`FoeFluxMonitor`	`FluxMonitor`	confirm: `the FOE quad electrometers (bim1 / bim2 on XF:11BMA-BI{IM:1}) reading incident flux; the channel map is DET-1`	FOE incident-flux monitors (quad electrometers); scalar current readings (DET-1)	`new` `confirm`
