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¶
The P64 undulator source and the optics hutch: the Tsai-geometry double-crystal monochromator with its coupled undulator energy axis, and the two harmonic-rejection / focusing mirrors.
Enclosure: p64-oh.
Note
The energy axis couples the DCM and the undulator (coupledmonoundmove / energy_all). The mirror pair is exposed as labelled axes (Mirror1, Mirror2) on p64/motor.
