Open questions¶

What CORA needs the P08 team to confirm before the model can be trusted.

P08 was reverse-engineered from P08's own public OnlineXML device registry (gitlab.desy.de/petra-iii-debian-packages/python-nxstools-extras-p08, branch debian/jessie) and a verified research brief, not from a live connection. The registry carries real Tango device names and control handles, but no crystal cuts or energy calibration. P08 is CORA's twelfth PETRA III beamline, the high-resolution diffraction 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: an optics hutch feeding the diffractometer experiment endstation?	A `p08-oh` optics hutch and a `p08-eh` endstation.	The Enclosure grouping.
SRC-1	Nice-to-have	The undulator period and parameters.	An undulator; gap read, period pending.	The source Asset detail.
GROUP-1	Nice-to-have	The per-axis roles of the `diff*` Kohzu diffractometer / sample bank.	Grouped as the `Goniometer` Asset carrying the bank prefix; per-axis roles pending.	The diffractometer Asset boundaries.

Source and optics¶

ID	Priority	Question	CORA assumes	Resolves
OPT-1	Blocks-go-live	The DCM and multilayer monochromator crystal cuts / d-spacing, and the CRL detail.	A DCM + a multilayer `Monochromator` and a `Transfocator` CRL; physical detail pending.	The optics modelling.

Sample endstation¶

ID	Priority	Question	CORA assumes	Resolves
DIFF-1	Blocks-build	The six-circle Kohzu diffractometer geometry and whether it composes a Diffractometer Assembly with a detector arm.	A `Goniometer` Asset (kozhue6cctrl + diff*), not the composed Diffractometer Assembly.	The diffractometer modelling.
SAMPLE-1	Nice-to-have	The sample hexapod geometry.	A `Hexapod`; geometry pending.	The sample modelling.

The detectors¶

ID	Priority	Question	CORA assumes	Resolves
DET-1	Blocks-go-live	The detector roster per experiment, the models (Eiger 1M / Pilatus / Mythen2 / PerkinElmer / Vortex), and whether the Mythen strip detector warrants a distinct Family.	A `Camera` suite plus a `EnergyDispersiveSpectrometer` Vortex; the Mythen modelled as a `Camera` for now.	The detector modelling.
HOST-1	Nice-to-have	A shared Lambda detector reports on the bare `petra3` host. Shared host, or registry artifact?	The Lambda is noted; the host is flagged.	The detector-to-host mapping.

Control and safety¶

ID	Priority	Question	CORA assumes	Resolves
CTRL-1	Blocks-go-live	The Tango device handles per P08 device, and whether the OnlineXML `debian/jessie` branch 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 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 high-resolution diffraction enter CORA's catalog as a Capability / Method?	Deferred: carried as a pending Practice reusing the `diffraction` slug; none coined.	The technique Capability.
