Generated from the descriptor

This page is generated from the descriptor at deployments/pdf/beamline.yaml. Edit the descriptor, not this page.

The device handles are read from the facility's public controls configuration and verified against it; vendor parts, energies, and physical positions are not in it and are carried confirm until beamline staff verify them. Source: NSLS2/pdf-profile-collection.

Enclosures

Enclosure Role Facility Permit signal
28-ID-1-A optics-hutch nsls2 confirm: PSS search-and-secure permit leaf not in source; only the fast shutter (XF:28ID1B-OP{PSh:1-Det:2}) and a photon shutter are exposed, not the front-end PPS leaves (PSS-1)
28-ID-1-B experiment-hutch nsls2 confirm: PSS permit leaf unknown; 28-ID-1-B is the PDF / total-scattering endstation carrying the spinner, detector towers, and sample environment (PSS-1)

The beamline

XPD's twin on the shared 28-ID wiggler: high-energy total scattering onto large flat-panel detectors, with an explicit two-detector, two-distance acquisition for wide-Q PDF.

  • Source: the beam, produced and conditioned before the sample.
  • Sample: the sample environment and its positioning.
  • Detector: what records the beam after the sample.
  • Controls: the control plane CORA's edge conducts over.

Not yet documented

This beamline has no Operations runbook and no live Experiment view, because CORA does not drive it yet. Both pages describe what an operator does with a running system, so writing them for a beamline CORA only models would be invention rather than documentation. The pilot at 2-BM carries both, and shows the shape they take once a deployment goes live.
