What CORA needs the P22 team to confirm before the model can be trusted.
P22 was reverse-engineered from P22's own public OnlineXML device registry (gitlab.desy.de/petra-iii-debian-packages/python-nxstools-extras-p22, branch debian/jessie) and a verified research brief, not from a live connection. The registry shows P22 sharing the P09 optics chain, with the HAXPS endstation as a grouped bank and the electron analyzer not exposed. P22 is CORA's fourteenth PETRA III beamline, the HAXPES 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.
The hutch grouping: shared P09 optics feeding the HAXPS experiment endstation?
A p22-optics (shared with P09) and a p22-haxps endstation.
The Enclosure grouping.
SHARED-1
Blocks-go-live
The P22 / P09 shared optics: the undulator, DCM, mirrors, and phase retarder are P09 devices. How are the two beamlines coordinated (shared straight, switched source, simultaneous operation)?
The optics are shared, homed in p22-optics with the relationship flagged.
The shared-optics coordination model.
SRC-1
Nice-to-have
The undulator period and parameters.
A shared P09 undulator; gap read, period pending.
The source Asset detail.
GROUP-1
Nice-to-have
The per-axis roles of the HAXPS manipulator bank (the polar / azimuthal / translation axes).
Grouped as one Manipulator Asset; per-axis roles pending.
The HAXPES electron analyzer model (a hemispherical analyzer, e.g. SPECS / Scienta), its lens modes, and its control interface (absent from this registry slice).
An ElectronAnalyzer Asset (the NSLS-II ESM Family); model and control pending.
The Tango device handles per P22 device, the shared P09 optics handles, 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; optics shared with P09.
Binding each Asset's control handle.
PSS-1
Blocks-go-live
The DESY personnel-safety permit signals, the shared-optics permit coupling with P09, 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 (HAXPES needs UHV at the analyzer) 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.
