Open questions

What CORA needs the P61 team to confirm before the model can be trusted.

P61 was reverse-engineered from P61's own public OnlineXML device registry (gitlab.desy.de/petra-iii-debian-packages/python-nxstools-extras-p61, branch debian/stretch) and a verified research brief, not from a live connection. The P61 registry is thin: one generic motor bank, no source / press / detectors exposed. P61 is CORA's seventeenth PETRA III beamline, the high-energy white-beam wiggler beamline. Each row below is a fact the beamline team owns, not a CORA modelling choice (those are on Model). It is a delete-on-answer queue. Priorities are Blocks-build, Blocks-go-live, and Nice-to-have.

Topology and scope

ID Priority Question CORA assumes Resolves
ENC-1 Blocks-go-live The hutch grouping: a single experiment hutch (the registry exposes one host), and the P61A / P61B branch split? A p61-eh2 experiment hutch, from the OnlineXML hasnp61eh2 host. The Enclosure grouping.
GROUP-1 Nice-to-have The per-axis roles of the eh_mot* motor bank. Grouped as one LinearStage stage carrying the bank prefix; per-axis roles pending. The Asset boundaries.

Source and optics

ID Priority Question CORA assumes Resolves
SRC-1 Blocks-go-live The damping-wiggler source parameters (period, field), and whether the beam is white or monochromated per branch. A damping wiggler delivering high-energy white beam; parameters pending. The source Asset detail.

Sample endstation

ID Priority Question CORA assumes Resolves
PRESS-1 Blocks-build The Large Volume Press (P61A): its press / anvil control, and whether it should bind the catalog PressureCell Family. A pending press; would reuse the catalog PressureCell (graduated across 13-id and P02) when exposed. The press modelling.

The detectors

ID Priority Question CORA assumes Resolves
DET-1 Blocks-go-live The energy-dispersive (Ge solid-state) detector, and any area detectors, absent from this registry slice. A pending EnergyDispersiveSpectrometer placeholder; the chain not invented. The detector modelling.

Control and safety

ID Priority Question CORA assumes Resolves
CTRL-1 Blocks-go-live The Tango device handles per P61 device, and whether the OnlineXML debian/stretch branch (unusual for the set) matches the live Tango database. The handles read from the public OnlineXML, carried pending; the floor is Tango + Sardana. Binding each Asset's control handle.
PSS-1 Blocks-go-live The DESY personnel-safety permit signals, the white-beam shielding / interlock, and the photon / front-end shutters (absent from the OnlineXML). Permit leaves and shutters to be named; not invented here. The Enclosure permit signals and the safety tier.
SUP-1 Nice-to-have The vacuum extent and the cooling / beam supplies. Photon beam, cooling water, vacuum. The Supply observations.
GOV-1 Nice-to-have The DESY operator pool and safety-review structure (site-level). Carried pending on the PETRA III Site, not instantiated per beamline. The governance principals.

Technique

ID Priority Question CORA assumes Resolves
TECH-1 Nice-to-have Does energy-dispersive diffraction enter CORA's catalog as a Capability / Method? Deferred: carried as a pending Practice reusing the energy_dispersive_diffraction slug; none coined. The technique Capability.
