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.

Source	insertion-device (confirm: P02 is an undulator beamline (high-energy diffraction); the OnlineXML exposes the undulator gap (p02/attributemotor/gap) but no period or parameters, carried pending (SRC-1))

Source¶

The P02 undulator source and the OH1 optics: the double-crystal monochromator, the horizontal- and vertical-focusing bendable mirrors, the defining slits, and the CRL. P02 shares the high-heatload optics hutch with P03.

Enclosure: p02-oh1.

Note

DCM is dcmmotor (bragg / parallel / perp) + dcmener. The HFM / VFM mirrors are bendable, exposed as curvature / ellipticity / tilt / z attribute motors. The OH1 p02/motor bank carries the optics positioning, roles not labelled (GROUP-1).
