P21

Swedish Materials Science high-energy diffraction (P21.2) and total scattering / PDF (P21.1) across an optics hutch, an EH3 endstation, and a LAB station; a thin reuse-and-reinforce scaffold (grouped motor banks, detectors carried pending), reusing the pending diffraction / total_scattering Methods.

Property Value
Facility PETRA III (Tango / Sardana)
Sector P21
Source insertion-device
Modelled reverse-engineered, full coverage

Generated from the descriptor

This page is generated from the descriptor at deployments/p21/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: python-nxstools-extras-p21.

The beamline

High-energy X-ray diffraction (Swedish Materials Science, P21.1 / P21.2): powder and single-crystal diffraction of bulk and engineering samples across several stations.

  • 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.
