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: P04 is a variable-polarization (APPLE-II-type) undulator beamline, 250-3000 eV; the OnlineXML exposes the undulator and its gap (p04/undulatorp04) but no period, polarization modes, or row-phase axes, carried pending (SRC-1))

Source¶

The P04 variable-polarization undulator. The OnlineXML exposes the undulator device and its gap; the polarization modes (horizontal / vertical / circular) and the row-phase axes that set them are not in the registry.

Enclosure: p04-optics.

Note

Undulator on p04/undulatorp04; the APPLE-II row-phase / polarization control is SRC-1.

Optics¶

The soft X-ray conditioning optics: the plane-grating monochromator that energy-selects the beam, the three mirrors that collimate / focus / refocus it, and the exit slit that sets the resolving power.

Enclosure: p04-optics.

Note

Handles read from the OnlineXML (p04/monop04, p04/spk for the mirror axes, p04/slt for the exit slit). The grating line densities, mirror coatings, and exit-slit calibration are OPT-1. These optics report on the haspp04exp2 host but are the optics section (HOST-1).
