Alvra

hard X-ray femtosecond pump-probe (time-resolved XAS / XES / HERFD and serial crystallography) on the SwissFEL Aramis branch; CORA's second XFEL, reinforcing the LCLS-MFX family-fold and acquisition-gap findings from an independent control stack (eco).

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

Enclosures

Enclosure Role Facility Permit signal
Aramis-Optics optics-hutch psi confirm: SwissFEL PPS search-and-secure signal TBD; the Aramis optics are shared across the Aramis stations (TOPO-1, PSS-1)
Alvra experiment-hutch psi confirm: SwissFEL PPS + pump-probe laser interlock TBD (PSS-1, LASER-1)

The beamline

A soft / tender XFEL endstation on PSI's Aramis branch (pump-probe spectroscopy, von Hamos emission); CORA's second XFEL, mined from an independent control stack, confirming the device families fold and the gaps are architectural.

  • 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.
