Open questions

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

HEX was reverse-engineered from public sources (the BNL beamline page, the beamline 27-ID wiki, and the beamline's bluesky profile collection NSLS2/hex-profile-collection and NSLS2/hextools), so the control handles in the Inventory are read from public config rather than confirmed by staff. 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	Are the six designed enclosures A (FOE), B, C, D, E, F, with only A and F presently relevant to operations (B not erected; C / D / E future-upgrade shells)?	All six declared; hex-foe and hex-endstation carry devices, B to E are device-free forward-looking shells.	The Enclosure grouping and the future-hutch contents.
SAT-1	Nice-to-have	Is the satellite building housing the F-hutch the same as Bldg. 742 or a separate numbered structure adjacent to it?	The F-hutch is a distinct enclosure adjacent to Bldg. 742, bound to the NSLS-II Site.	The endstation Enclosure detail.
LAYOUT-1	Nice-to-have	The source-to-F-hutch distance (about 100 m) and whether an exact per-hutch z-position table exists.	About 100 m source to endstation; no per-hutch z table carried.	The beam-path geometry.
BRANCH-1	Nice-to-have	Do the inboard and outboard front-end branches carry any installed optics, or are they bare provisions for the future hutches?	Provisions only; only the center branch carries devices.	The front-end slit modelling.

Source and optics

ID	Priority	Question	CORA assumes	Resolves
MACHINE-1	Nice-to-have	The storage-ring state HEX reads (current, fill, status).	Observe-only machine state, a loose StorageRing; the exact PVs pending.	The machine-state observation.
SCW-1	Nice-to-have	The superconducting wiggler pole count and critical photon energy (only the 4.3 T field, 70 mm period, 1.2 m length, cell-27 straight are published).	An InsertionDevice Asset; field, period, and length carried as specs; pole count and critical energy pending.	The source Asset detail.
MONO-1	Blocks-go-live	The monochromator crystal material and geometry (is it Si(111) bent Laue?), the crystal count, and the d-spacing.	A single bent-Laue first crystal on a vertical translation, binding Monochromator; the incident energy a PseudoAxis over it.	The monochromator and incident-energy Assets.
MONO-2	Blocks-build	The upper monochromatic energy: 150 keV (the wiki) or 200 keV (peer-reviewed, "first NSLS-II beamline to reach 200 keV mono")?	30 to 200 keV monochromatic, 30 to 250 keV white.	The energy-axis range bound.
FILT-1	Nice-to-have	The FOE low-energy filter materials and thicknesses per branch (center SiC 3 / 6 / 9 / 12 mm; outboard / inboard Cu plus SiC) and the 35 mm pitch.	Beam-hardening filters bound to Filter; materials and thicknesses as listed on the commissioning wiki.	The filter Asset detail.
FOCUS-1	Nice-to-have	What focusing optic is being commissioned for the monochromatic beam, and the target focused spot.	Focusing not yet a device; carried deferred.	The focusing-optic Asset.

Sample

ID	Priority	Question	CORA assumes	Resolves
STAGE-1	Blocks-go-live	The modular sample-tower configurations (A to D), the 500 kg capacity, and which axes are motorized (the tomographic rotation and the translations).	One reconfigurable tower (Table, 500 kg, configs A to D) plus a RotaryStage rotation and LinearStage translations; capacity and config set as settings.	The sample-stage modelling.
INSITU-1	Blocks-go-live	Which in-situ rigs are actually installed or available at the endstation (load frames, furnaces, cryostats, battery cyclers)?	None installed; the endstation is "capable of housing" user-brought environments, so no in-situ rig is modelled.	The sample-environment modelling; the CORA family decision is on Model.

Detection

ID	Priority	Question	CORA assumes	Resolves
DET-1	Blocks-go-live	The PerkinElmer area-detector model (XRD1621?), its pixel count, and that it is the angle-dispersive / powder-diffraction (ADXD) detector.	A PerkinElmer XRD1621 flat panel binding Camera, inferred to be the ADXD detector.	The area-detector modelling.
DET-2	Blocks-go-live	The GeRM germanium strip detector channel count, energy resolution, and the EDXD gauge-volume dimensions.	A GeRM strip detector binding the existing EnergyDispersiveSpectrometer Family; specs pending.	The energy-dispersive-detector modelling.
DET-3	Nice-to-have	Which Kinetix camera is the tomography default, and the scintillator / lens magnification options behind the "2 & 4 mm", "20 & 40 mm", and "Dual cam" imaging-table positions.	kinetix1 is the default; the scintillator-lens table binds Scintillator; the Phantom Veo is the high-speed camera.	The imaging-camera and scintillator modelling.

Control and safety

ID	Priority	Question	CORA assumes	Resolves
CTRL-1	Blocks-go-live	Are the EPICS PV handles read from the profile collection current and correct, and what are the FOE-optics PVs (absent from it)?	The endstation detector handles are from the profile collection and carried confirm; the FOE-optics PVs are pending.	Verifying each Asset's control handle.
PSS-1	Blocks-go-live	The PSS search-and-secure permit signals and the photon / front-end shutters (absent from the profile collection).	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 (the FOE optics) and the cooling supply.	Photon beam, cooling water, and vacuum on the FOE optics; the cryogen-free wiggler draws no liquid helium.	The Supply observations.
GOV-1	Nice-to-have	The NSLS-II operator pool and safety-review structure (site-level), and the NYSERDA-aligned beamtime-reservation fraction and the proposal-evaluation committee's scoring split.	Carried pending on the NSLS-II Site; the NYSERDA allocation Policy layered on top, fraction and scoring pending.	The governance principals and allocation Policy.

Technique

ID	Priority	Question	CORA assumes	Resolves
TECH-1	Blocks-go-live	Is the operational technique set exactly imaging / tomography, radiography, EDXD, and powder / ADXD, with all three diffraction-and-imaging modes available in the one endstation, and are PDF and 3DXRD not offered?	Those techniques only; multi-technique in one endstation via detector / optics positioning; no PDF, no 3DXRD.	The technique Capabilities and the multi-technique modelling.
