Source

The incident beam, produced, conditioned, and defined before the sample. The controllers that drive these devices are on the Controls page. Each device pairs its human name with its control 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	8.3.2
Tier	Unit
Source	bending-magnet (confirm: 8.3.2 is fed by a Superbend (superconducting bending magnet); the field and critical energy are not in the public data record, carried pending (SRC-1))

Machine

The machine-level source state, observed not driven.

Enclosure: 8-3-2-hutch.

Note

The ALS storage-ring state, the loose StorageRing pattern reused across the fleet. The data record carries /measurement/instrument/source/source_name and /measurement/instrument/source/current (MACHINE-1).

Name	Family	PV	Key specs	Replaceable	Status
StorageRing	StorageRing		ALS storage-ring state (source_name, ring current); observe-only. Structure from /measurement/instrument/source/{source_name,current,beam_intensity_incident}; live handle pending (MACHINE-1, CTRL-1)		new confirm

Source magnet

The Superbend, the superconducting bending-magnet source delivering the hard X-ray beam (6,000-43,000 eV).

Enclosure: 8-3-2-hutch.

Note

The Superbend is recorded as a Supply (PhotonBeam) at the Site, identity-only here, the 2-BM bending-magnet precedent. Field and critical energy pending (SRC-1).

Name	Family	PV	Key specs	Replaceable	Status
Superbend	InsertionDevice		device type: superconducting-bending-magnet (Superbend) the Superbend source feeding 8.3.2 (6-43 keV); recorded as a Supply (PhotonBeam) at the Site, identity-only here. Field, critical energy, and live handle pending (SRC-1, CTRL-1)		new confirm

Optics

The conditioning optics: a monochromator setting the incident energy, the beam-defining slits, and the attenuating filter. 8.3.2 operates 6,000-43,000 eV.

Enclosure: 8-3-2-hutch.

Note

The monochromator binds Monochromator; the slits bind Slit; the attenuator binds Filter. Structure is read from the DXfile data record; multilayer / crystal detail and live handles pending (MONO-1, OPT-2, FILT-1, CTRL-1).

Name	Family	PV	Key specs	Replaceable	Status
Monochromator	Monochromator		energy range: 6,000 to 43,000 eV the energy-setting monochromator; the data record exposes /measurement/instrument/monochromator/energy as the master energy and the setup channels Z2, turret1, turret2 (the multilayer / mirror turrets) plus crystal-temperature monitors temperature_tc2 / temperature_tc3. The mechanism (multilayer vs crystal), d-spacing, and live handles are pending (MONO-1, CTRL-1)
	new confirm
BeamSlit	Slit		the beam-defining slits; the data record exposes a horizontal slit (hslits_A_Door, hslits_A_Wall, hslits_center, hslits_size) and a vertical slit (vslits_Lead_Flag). The full blade-axis map and live handles are pending (OPT-2, CTRL-1)
	new confirm
BeamFilter	Filter		the attenuating filter; the data record exposes /measurement/instrument/attenuator/setup/filter_y (the filter-position axis). Filter materials and thicknesses are pending (FILT-1, CTRL-1)
	new confirm
