Open questions

What CORA needs the I-TOMCAT team to confirm before the model can be trusted.

I-TOMCAT is a modelling exercise modelled from PSI's public pages and the SLS 2.0 design reports, so this page is long by design: almost every value in the Inventory is read from a public page, not a staff-confirmed fact, and some are legacy TOMCAT specs whose validity for the rebuilt beamline is itself uncertain. Each row below is a fact the beamline team or a design report owns, not a CORA modelling choice. It is a delete-on-answer queue: when an item is answered, the answer lands in the descriptor and the row is removed (with the reason in the commit). Priorities are Blocks-build (needed before the model is built for real), Blocks-go-live (needed before first users), and Nice-to-have.

Control and safety

ID Priority Question CORA assumes Resolves
CTRL-1 Blocks-build What are the EPICS PV prefix scheme and the BEC ophyd device handles for each I-TOMCAT device? The PV scheme is not public and the BEC plugin is internal; CORA leaves each device handle empty. Wiring each Asset to a real control handle.
SEAM-1 Blocks-build Does CORA's edge replace BEC's scan/experiment orchestration, or drive through it at the ophyd/bec_messages boundary? CORA's edge replaces BEC's scan steering, conducting over EPICS; the shared ophyd device model keeps a drive-through reading open. The control-stack seam boundary.
PSS-1 Blocks-build What are the PSS permit signals and access-interlock names for the optics and experiment hutches? Both hutches exist with permit signals to be named. The Enclosure permit signals.
ENC-1 Blocks-go-live Is X02SA genuinely the rebuilt I-TOMCAT, and what is the optics/experiment hutch grouping? X02SA is I-TOMCAT (corroborated by the /sls/x02sa/ raw-data path); two hutches, optics shared with S-TOMCAT. The enclosure model and sector binding.

Sources and optics

ID Priority Question CORA assumes Resolves
SRC-1 Blocks-go-live What are the U15 undulator period and gap range, and when does the HTSU10 source upgrade land? A U15 undulator now, HTSU10 in 2027; period/gap to be named. The InsertionDevice settings.
MACHINE-1 Nice-to-have What are the SLS 2.0 storage-ring state handles (current, fill) CORA observes? Observe-only ring state, handles to be named. The StorageRing observation handles.
MONO-1 Blocks-go-live Do the legacy DCMM optics (multilayer stripes, Si(111), energy range) still describe the rebuilt beamline? The legacy fixed-exit DCMM, 8-50 keV (8-30 recommended), carried until confirmed. The Monochromator / Window / Filter specs.
OPT-1 Nice-to-have What are the focusing / harmonic-rejection mirror coatings and handles? They are not on the public pages. A focusing mirror exists but is deferred (not invented) until named. The Mirror model.
OPT-2 Nice-to-have What is the beam-defining slit blade-axis map and the handles? Beam-defining slits ahead of the endstation; axis map to be named. The Slit model.

Endstation

ID Priority Question CORA assumes Resolves
STAGE-1 Blocks-go-live Is the rotation stage the Aerotech ABRX150, and are its specs (~1500 deg/s) final? The "(target)" ABRX150, used as the trigger master clock. The rotary stage Model binding.
SAMPLE-1 Blocks-go-live What are the sample positioning axis set, the slip-ring channel count, and the fast-shutter model? A centring stage, a continuous-rotation slip ring, and a dose-limiting fast shutter; details to be named. The sample-stage models.
TRIG-1 Blocks-go-live Does the air-bearing rotary TTL feed the camera triggers directly, or is a conditioner needed? Direct rotary-master triggering; may evolve once camera trigger requirements firm. The trigger / sync chain.

Detector

ID Priority Question CORA assumes Resolves
DET-1 Blocks-go-live Which camera models are installed (the pco.edge family, pco.dimax, and the PSI GigaFRoST)? Three cameras at the stated design-target sensors/speeds; models unbound. The camera Model bindings.
DET-2 Blocks-go-live What is the microscope optics model, and does it compose the cross-facility Microscope Assembly the way 2-BM does? A Housing with Objective + Scintillator constituents, 1x-40x; Assembly composition deferred. The microscope Model and Assembly composition.

Techniques

ID Priority Question CORA assumes Resolves
TECH-1 Nice-to-have Which tomography Practices does the rebuilt beamline offer (e.g. is grating interferometry offered)? Standard + phase-contrast + dynamic 4D tomography; grating interferometry out of scope. The SLS Practices that bind the catalog Methods.
