Techniques

What the modelled part of P24 is designed to do, as intent. First cut.

A technique is a portable Catalog Method; a Practice is how a facility adapts it. P24's chemical crystallography earns no dedicated catalog Method today, so the Method below renders unlinked and is carried pending until a technique enters scope (TECH-1).

Chemical crystallography

P24 mounts a single crystal on the diffractometer and collects single-crystal diffraction on the area detector to solve small-molecule / chemical structures (including at non-ambient conditions).

Technique Catalog method Notes
Single-crystal / chemical crystallography diffraction single-crystal diffraction on the EH2 diffractometer + area detector; reuses the diffraction slug (no dedicated chemical-crystallography Method exists), a further consumer (TECH-1)

A chemical crystallography beamline on familiar vocabulary

P24 is PETRA III's chemical (small-molecule) crystallography beamline, the fleet's second after Diamond I19. It is distinct from the macromolecular-crystallography beamlines (P11, i03, FMX / AMX, MANACA, TPS): those bind the Goniometer Family and the mx_data_collection Method, while P24 does small-molecule chemical crystallography, which CORA models as diffraction for now (no dedicated chemical-crystallography Method exists, and the registry does not expose a labelled goniometer). The instrument anatomy reuses existing Families (LinearStage, Slit, EnergyDispersiveSpectrometer); the area detector is carried pending.

Not modelled yet

The concrete acquisition recipes (the single-crystal data-collection strategies, the multi-temperature / variable-condition collection) are not written yet; they join as the deployment approaches the point where CORA drives P24. Whether a dedicated chemical-crystallography Method (vs reusing diffraction) enters CORA's catalog is an owner-scope decision on Model; see Open questions for the world-facts to confirm first.
