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.

Insertion devices

Two switchable straight-section sources. The undulator drives high-flux micro- and nano-tomography; the wiggler drives wide-field large-FOV white-beam microtomography. The operation mode selects which is in use.

Enclosure: TomoWISE-optics.

Note

z is measured from the straight-section centre here (CPMU14 at -505 mm, 3T3PW at +1734 mm). All specifications are TDR design targets.

CPMU14	InsertionDevice		device type: cryogenic-permanent-magnet-undulator period: 14 mm min gap: 3.8 mm length: 2.0 m (cryostat 2.67 m) max k eff: 1.84 power at 500ma: 11.1 kW primary source for high-flux micro- and nano-tomography		new confirm
3T3PW	InsertionDevice		device type: three-pole-wiggler field: 3 T magnetic length: 412 mm min gap: 11 mm power at 500ma: 1.6 kW wide-field large-FOV white-beam microtomography		new confirm

Front end

Fixed and movable masks plus the heat absorber that shape the beam and absorb power before the optics hutch.

Enclosure: TomoWISE-optics.

Note

z from the CPMU14 source (TDR Table 7.1). Mask is now a shared catalog Family; the heat-absorber Family is not yet in the catalog (it renders as plain text pending the passive beam-path tier), bound loosely by design intent.

Optics hutch

The conditioning optics that filter, monochromate, and define the beam delivered to the experiment hutch. Diagnostic modules DM1/DM2 carry the bremsstrahlung collimators, white-beam stops, slits, and beam-position monitors.

Enclosure: TomoWISE-optics.

Note

z from the straight-section centre (TDR Table 8.1). Filter / BPM / collimator / beam-stop Families are not all in the catalog yet and render as plain text.

Safety shutters

The safety unit (SU) gating the beam between the optics and experiment hutches.

Enclosure: TomoWISE-optics.
