PETRA III¶
PETRA III is a Federation Facility (FacilityKind = Site): the home for the facility-level facts an experiment inherits but does not own. The beamlines it hosts link up to this page rather than restating it.

The beamlines¶
What CORA models at PETRA III. Each row's badges and one-line summary are read from the beamline's own descriptor; follow the link for the full model.
| Beamline | Maturity | Evidence | Coverage | What it is |
|---|---|---|---|---|
| P01 | Model | Controls config | Full | nuclear resonant scattering and inelastic / resonant-inelastic scattering (2.5-80 keV) across two optics hutches and three experiment hutches (EH1 NRS high-resolution-monochromator stack, EH2 diffraction, EH3 RIXS / KB pair); reuses the optics / motion Families, novelty is the Site, its Tango / Sardana control plane read from the OnlineXML, and the NRS / RIXS technique branch (reusing the pending IXS / RIXS Methods) |
| P04 | Model | Controls config | Full | variable-polarization soft X-ray spectroscopy (250-3000 eV: XAS, photoemission) across a soft X-ray optics section and two experiment endstations; CORA's first GratingMonochromator deployment (the plane-grating mono), reuses the optics / motion Families otherwise, reusing the pending xas_spectroscopy / angle_resolved_photoemission Methods |
| P06 | Model | Controls config | Full | hard X-ray scanning micro / nano fluorescence and diffraction microscopy + nano-tomography across an optics hutch and two scanning-probe endstations (MC01 micro, NC1 nano); the fleet's fullest scanning-probe instrument (the Maia XRF array as EnergyDispersiveSpectrometer, hexapods, Aerotech fly-scan stages), coins no new Family, reusing the pending scanning_fluorescence_microscopy / tomography Methods |
| P11 | Model | Controls config | Full | high-throughput macromolecular crystallography (rotation MX) and bio-imaging on a goniometer + Pilatus detector with cryostream cooling; PETRA III's first MX beamline, a reuse-and-reinforce deployment coining no new vocabulary (reuses the i03 MX vocabulary and the pending mx_data_collection / tomography Methods); a sparse registry, so the experiment hutch is modelled as grouped stages with the goniometer carried as a question |
| P03 | Model | Controls config | Full | micro- and nanofocus small- and wide-angle X-ray scattering (SAXS / WAXS, 9-23 keV) across shared P02 / P03 optics and two endstations (a microfocus endstation and the nanofocus GINIX waveguide endstation); PETRA III's first SAXS / WAXS beamline, coins no new Family, brings Galil DMC and SmarPod controllers, reusing the pending small_angle_scattering / wide_angle_scattering Methods |
| P10 | Model | Controls config | Full | coherent hard X-ray applications (XPCS, coherent diffraction imaging / ptychography) across an optics hutch and three experiment areas (E1 coherent imaging, E2 XPCS / diffraction, LAB); a further XPCS beamline (after APS 8-ID and NSLS-II CHX) and the first PETRA III practice to bind a graduated catalog Method (xpcs, earned at 8-ID) rather than a pending slug; coins no new Family, with the widest detector suite in the set |
| P09 | Model | Controls config | Full | resonant scattering, diffraction, and high-field magnetism (XMCD, magnetic scattering) across a resonant-scattering hutch, a diffraction hutch, and a 14 T magnetism endstation; a further consumer of the 4-ID polarization / magnetism vocabulary (the catalog PhaseRetarder, PolarizationAnalyzer, and Magnet Families), coins no new Family, reusing the pending resonant_scattering / magnetic_scattering / xmcd Methods |
| P02 | Model | Controls config | Full | high-energy hard X-ray diffraction: P02.1 powder diffraction / total scattering / PDF (~60 keV) + P02.2 extreme conditions (diamond-anvil-cell high-pressure diffraction); the fleet's second diamond-anvil-cell deployment (binds the catalog PressureCell, graduated across 13-ID and P02), bendable HFM / VFM mirrors, coins no new Family, reusing the pending powder_diffraction / total_scattering Methods |
| P64 | Model | Controls config | Full | advanced X-ray absorption spectroscopy (dilute / high-rate fluorescence EXAFS / XANES) on a Tsai DCM + a multi-element fluorescence detector (104-channel SIS3302); the advanced half of the PETRA III XAS pair, coins no new Family, reusing the pending xas_spectroscopy Method |
| P65 | Model | Controls config | Full | applied / high-throughput X-ray absorption spectroscopy (transmission + fluorescence EXAFS / XANES) on a channel-cut DCM, sharing the P64 optics host; the applied half of the XAS pair, a thin reuse-and-reinforce scaffold (detection carried pending), reusing the pending xas_spectroscopy Method |
| P07 | Model | Controls config | Full | high-energy materials-science diffraction (HEMS) on a multi-bounce DCM + four-circle diffractometer, with a 17 T high-field magnet endstation; jointly operated by Helmholtz-Zentrum Hereon + DESY, coins no new Family (a further consumer of the graduated Magnet Family), reusing the pending diffraction / magnetic_scattering Methods |
| P08 | Model | Controls config | Full | high-resolution diffraction (surface / interface, reflectivity, powder / single-crystal) on a six-circle Kohzu diffractometer with a rich detector set (Eiger / Pilatus / Mythen / PerkinElmer / Vortex); coins no new Family, reusing the pending diffraction Method |

| P22 | Model | Controls config | Full | hard X-ray photoelectron spectroscopy (HAXPES) on a Manipulator sample stage + ElectronAnalyzer, sharing the P09 optics chain (undulator / DCM / mirrors / phase retarder); coins no new Family, reusing the pending angle_resolved_photoemission Method; the fleet's first shared-optics beamline pair |
| P23 | Model | Controls config | Full | in-situ / operando X-ray diffraction and imaging; a thin reuse-and-reinforce scaffold (one grouped motor bank, optics / diffractometer / detectors carried grouped / pending), reusing the pending diffraction Method |
| P24 | Model | Controls config | Full | single-crystal / small-molecule chemical crystallography across an optics hutch and two experiment hutches (EH1 / EH2); coins no new Family (the small-molecule diffractometer reuses LinearStage, area detector pending), reusing the pending diffraction Method |
| P61 | Model | Controls config | Full | high-energy white-beam wiggler beamline (P61A Large Volume Press + P61B energy-dispersive diffraction); a thin reuse-and-reinforce scaffold (one grouped motor bank, source / press / detectors pending), reusing the pending energy_dispersive_diffraction Method; the last PETRA III beamline with a public OnlineXML registry |
| P13 | Model | Controls config | Full | EMBL Hamburg macromolecular crystallography (rotation MX); CORA's first EMBL Hamburg beamline, MXCuBE HardwareObjects source |
| P14 | Model | Controls config | Full | EMBL Hamburg high-end two-endstation macromolecular crystallography (MX), the sibling of P13 |
Nineteen beamlines on the PETRA III ring read from a common Tango / Sardana OnlineXML registry; several share optics (P22 runs off the P09 chain).
The techniques adapted here¶
A Practice is PETRA III's facility-tuned form of a cross-facility Method: the ISA-88 Site Recipe layer. The Method names a technique abstractly in the Catalog; the Practice is how the beamline runs it here. Each row links up to the Method it adapts.

Planned: 30 further Practices.
Safety and governance¶
Access at PETRA III is gated by the facility safety system (DESY personnel safety system, pending); the principal roster is pending; no autonomous agents run here today.
How this maps to CORA's model¶
PETRA III is a Federation Facility (FacilityKind = Site, facility_code = "petra-iii"); the beamlines above are its root Assets (tier = Unit), and their sub-systems nest below by parent_id. See the CORA model for the aggregate shapes.
