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: P07 is an undulator beamline (high-energy materials science, jointly operated by Helmholtz-Zentrum Hereon 2/3 + DESY 1/3); the OnlineXML exposes the undulator (p07/undulator) and its gap / taper (p07/attributemotor) but no period or parameters, carried pending (SRC-1, OPERATOR-1))

Source¶

The P07 undulator source and the optics: a multi-bounce double-crystal monochromator (two crystals, each with bend / pitch / roll / yaw) for high-energy operation, plus the OH2/OH3 defining slits.

Enclosure: p07-oh2.

Note

The DCM is exposed as named 1st / 2nd-crystal axes (dcm_1st_, dcm_2nd_) plus the dcmenergy coupling. The OH slits are slt + galildmcslit virtual axes. A Beckhoff z-stage (zpos_shoh1) positions the OH1 component.
