Model

The developer's by-kind index: where each CORA aggregate's I20-1 content lives. It hosts no content of its own. Design-phase scaffold, deliberately partial.

For the aggregate shapes see the architecture model and the per-BC modules.

Aggregate (BC) Where at I20-1
Asset (Equipment) Inventory (in this zone)
Computed / virtual axes (Equipment) Inventory (EnergyAxis)
Capability, Method (Recipe) Techniques
Enclosure (Enclosure) The beamline (I20-1-OH optics, I20-1-EH experiment)
Zone, Conduit, Policy (Trust); Actor (Access) Governance

Deliberately not here yet

This is a design-phase scaffold (descriptor + docs), and a deliberately partial one: the dodal commissioning module is thin. Left out on purpose:

  • The dispersive heart of EDE. The bent-crystal polychromator (POLY-1) and the position-sensitive strip detector (STRIP-1), the two devices that make the technique energy-dispersive, are not in the public source, so they are named open questions, not modelled. The polychromator would be a genuinely new optic class (an energy-fanning bent crystal, distinct from Monochromator / GratingMonochromator); CORA would weigh a Polychromator Family once it is PV-bound, not before. Coining it from no source PV would be invention.
  • No new Family, no loose family. What is modelled reuses existing families only: the turbo slit binds Slit, the PMAC MotionController, the PandA TimingController, the sample stage the graduated Manipulator, the Xspress3 the graduated EnergyDispersiveSpectrometer.
  • The mock / skip honesty. The sample stage is a dodal mock (real PVs, motors being reconnected, STAGE-1); the Xspress3 is a dodal skip (defined, not loaded by default, DET-1). Both are carried confirm and flagged, not asserted live.
  • The absent source / optics / diagnostics chain. No source, front-end, primary mirror, attenuator, ion chamber, flux monitor, or beam-position monitor is in the commissioning module; the source is carried PV-less (SRC-1) and the rest are open questions.
  • No new Capability or Method. Energy-dispersive EXAFS is a pending Practice on the Site (the dispersive complement to the BMM energy-scan question, TECH-1); MX3-style, the technique is reinforced-and-deferred, not coined.
  • Operations and experiment views, integration scenarios, vendor Models. A runbook and registered Assets for a beamline CORA does not yet drive, and whose primary detector is not even in source, would be invention; they land when the dispersive devices are PV-bound and the team confirms. The 2-BM Model page shows the shape a fully-modelled deployment carries.
