Model¶
The developer's by-kind index: where each CORA aggregate's ISS content lives. It hosts no content of its own. Design-phase scaffold.
For the aggregate shapes see the architecture model and the per-BC modules.
| Aggregate (BC) | Where at ISS |
|---|---|
| Asset (Equipment) | Inventory (in this zone) |
| Computed / virtual axes (Equipment) | Inventory (EnergyAxis) |
| Capability, Method (Recipe) | Techniques |
| Enclosure (Enclosure) | The beamline (8-ID-A optics, 8-ID-B experiment) |
| Zone, Conduit, Policy (Trust); Actor (Access) | Governance |
| Procedure, Recipe, Caution, Supply, Subject, Run, Campaign, Dataset, Decision | deferred (design-phase; see below) |
What this deployment graduates¶
ISS earns one catalog change: the EmissionSpectrometer Family GRADUATED. LCLS-MFX introduced it for its von Hamos six-crystal XES spectrometer and carried it loose at n=1 (SPEC-1, with MAX IV Balder noted as a near-sighting). ISS's Johann and von Hamos crystal emission spectrometers are the second sighting, earning the rule-of-three the way GratingMonochromator (CSX), Manipulator (ESM), and ElectronAnalyzer (SST) graduated at their second sighting. The abstraction is settled (a crystal-analyzer emission spectrometer composing analyzer crystals and a 2D detector along a Rowland-circle or wavelength-dispersive geometry is a distinct, recurring device, not a point Sensor and not a beam-conditioning Monochromator), so it GRADUATED into the catalog (SPEC-1); LCLS-MFX's references were swept loose to graduated alongside. It stays distinct from the still-loose EnergyAnalyzer (the IXS diced-crystal energy-selecting analyzer, ANALYZER-1) and SpectrometerArm (the SIX soft X-ray grating dispersive RIXS arm, RIXS-1), which graduate nothing until their own rule-of-three.
Deliberately not here yet¶
This is a design-phase scaffold (descriptor + docs), mirroring the other NSLS-II and Diamond beamlines. Left out on purpose:
- No new loose Family. ISS is otherwise a reuse deployment: the trajectory and high-resolution monochromators bind
Monochromator, the mirrorsMirror, the filter boxFilter, the slitsSlit, the shuttersShutter, the energy axisPseudoAxis, the sample stageLinearStage, the goniometerGoniometer, the reference foil wheelRotaryStage, the thermal stageTemperatureController, the ion chambersFluxMonitor, the Xspress3 SDDEnergyDispersiveSpectrometer, the PilatusCamera, the trajectory controllerMotionController, the analog pizza boxTimingController. - The held
BeamPositionMonitor. The beam-position diagnostics bind the looseBeamPositionMonitorfamily that several deployments use; it stays loose pending the sensor fold-vs-promote decision (DIAG-1). - No new Capability or Method. EXAFS leans on the deferred
energy_scanCapability (ENERGY-1, the BMM question; ISS strengthens it as a further consumer without forcing it); XES / HERFD reuse thexas_spectroscopyMethod LCLS-MFX left pending, the second consumer (TECH-1). ISS records that one pending Practice and coins nothing. The per-technique reduction isComputePortwork. - The deferred in-situ environment. The ion-chamber fill-gas mass-flow controllers (He / N2) and the broader in-situ sample environment fit no catalog family cleanly (the loose FlowController) and are named in a question (
ENV-1) rather than modelled at this design phase. ISS models the main transmission / fluorescence / emission legs as the representative configuration. - Operations and experiment views, integration scenarios, vendor Models. A runbook and registered Assets for a beamline CORA does not yet drive would be invention; they land when the design firms and the team confirms. The 2-BM Model page shows the shape a fully-modelled deployment carries.
