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.

Source¶
The undulator source and the machine-level storage-ring state it draws on.
Enclosure: i22-optics.
Note
The undulator parameters dodal carries (80 poles, 2.0 m) are dry facts; the energy range and gap-to-energy curve are calibration the deployment must supply (SRC-1). The storage-ring device is machine-shared and observe-only; its modelling boundary is open (MACHINE-1).

Conditioning optics¶
The mirrors, monochromator, and transfocator that focus, monochromate, and condition the beam.
Enclosure: i22-optics.
Note
Mirror internal axes (yaw/pitch/roll, jacks), the DCM crystal d-spacing and thermal reads, and the bimorph voltage channels are device internals carried as notes/settings, not separate Families (OPT-1). The transfocator binds the graduated Transfocator catalog Family (a CRL focusing optic).

Beam defining¶
The beam-defining slits along the conditioning path.
Enclosure: i22-optics.
Note
Five of the six are four-independent-blade slits (the catalog Slit shape exactly: x/y plus/minus blades forming a variable opening); slit 4 exposes gap+centre only, a fewer-DOF setting within the same Family.
