Bernina

hard X-ray femtosecond pump-probe diffraction / scattering on two reconfigurable diffractometers (GPS six-circle, XRD You-geometry); the second co-equal station on the shared Aramis source, makes the shared-switched-source seam concrete, reuses the graduated Diffractometer Assembly; a deliberately partial first cut (eco), the live device config is externalized. A deliberately partial first cut.

Property Value
Facility PSI (EPICS (SLS) + eco / slic (SwissFEL))
Source free-electron-laser
Modelled reverse-engineered, partial coverage

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: paulscherrerinstitute/eco.

The beamline

A hard X-ray XFEL diffractometer platform sharing the Aramis source with Alvra and Cristallina; the first deployment to make the switched-shared-source seam concrete as a second co-equal station.

  • 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.
