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.
