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
Facility	petra-iii
Sector	P03
Tier	Unit
Source	insertion-device (confirm: P03 is an undulator beamline (SAXS / WAXS, 9-23 keV); the OnlineXML exposes an undulator gap virtual axis (p03/attributemotor/gap) but no period or parameters, carried pending (SRC-1))

Source¶

The P03 undulator source and the shared conditioning optics: a multilayer monochromator, two mirrors, and the defining slits. P03 shares the high-heatload optics with P02.

Enclosure: p03-optics.

Note

The undulator gap is a p03/attributemotor virtual axis. The first defining slit reports on the P02 optics host (haspp02oh1, HOST-1).
