Open questions¶

What CORA needs the P03 team to confirm before the model can be trusted.

P03 was reverse-engineered from P03's own public OnlineXML device registry (gitlab.desy.de/petra-iii-debian-packages/python-nxstools-extras-p03, 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 focal sizes, multilayer d-spacing, or energy calibration. P03 is CORA's fifth PETRA III beamline and its first SAXS / WAXS 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: shared optics feeding a microfocus endstation and a nanofocus GINIX endstation?	A `p03-optics` section (shared with P02) and two `p03-microfocus` / `p03-nanofocus` endstations.	The Enclosure grouping.
HOST-1	Nice-to-have	The first defining slit reports on the P02 optics host (`haspp02oh1`) and a Lambda on the bare `petra3` host. Shared Tango DB hosts, or registry artifacts?	The shared P02 / P03 optics are homed in `p03-optics`; the hosts are flagged.	The device-to-host mapping.
GROUP-1	Nice-to-have	The per-axis roles of the motor banks (`expmi_mot01..64` microfocus, `mot01..40` nanofocus).	Grouped as sample-stage Assets carrying the bank prefix; per-axis roles pending.	The sample-stage Asset boundaries.

Source and optics¶

ID	Priority	Question	CORA assumes	Resolves
SRC-1	Nice-to-have	The undulator period and parameters.	An undulator; gap read, period pending.	The source Asset detail.
OPT-1	Blocks-go-live	The multilayer monochromator d-spacing, the mirror coatings, and the CRL / GINIX-waveguide focal sizes.	A multilayer `Monochromator`, two `Mirror`s, a CRL `Hexapod`, and the GINIX waveguide; handles read, physical detail pending.	The optics modelling.

Sample endstations¶

ID	Priority	Question	CORA assumes	Resolves
SAMPLE-1	Nice-to-have	The GINIX waveguide-to-sample geometry and the sample-hexapod / rotation detail.	A `Hexapod` sample stage and a `RotaryStage` rotation; geometry pending.	The GINIX sample modelling.
TEMP-1	Nice-to-have	The Eurotherm 2604 sample-environment sensor / setpoint handles.	A `TemperatureController` sample environment.	The temperature-control modelling.

The detectors¶

ID	Priority	Question	CORA assumes	Resolves
DET-1	Blocks-go-live	The detector roster per experiment, the SAXS-vs-WAXS assignment (Pilatus 300k / 1M), the sample-to-detector distance, and the fluorescence-detector channel count.	`Camera` Pilatus detectors plus `EnergyDispersiveSpectrometer` MCA / XIA detectors; assignment pending.	The detector modelling.

Control and safety¶

ID	Priority	Question	CORA assumes	Resolves
CTRL-1	Blocks-go-live	The Tango device handles per P03 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, the photon / front-end shutters, and the role of the GINIX experiment shutter (absent / partial in the OnlineXML).	Permit leaves and shutters to be named; the GINIX shutter bound to `Shutter`, safety role pending.	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), and the shared-optics permit coupling with P02.	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	Do small-angle and wide-angle X-ray scattering enter CORA's catalog as Capabilities / Methods?	Deferred: carried as pending Practices reusing the `small_angle_scattering` and `wide_angle_scattering` slugs; none coined.	The technique Capabilities.
