Inventory

The CORA Asset model for 7-BM: the planned device tree and what still needs confirming.

7-BM is in the design phase, so this is the planned Asset shape, not a registered inventory. It is the cross-cutting reference view of the Source walk and the Sample and Detector pages. The shape is generated-honest: it is authored from the same beamline.yaml descriptor that the Source page renders from.

Devices bind to catalog Families where one fits. No vendor Model is bound: the 7-BM docs name vendors (Photron, Sierra, Kaeser, IDT, Rigaku) but none is procured into the CORA catalog yet, so models are open questions, not bindings. Control handles are omitted because the EPICS PV names are not yet recorded here.

The Asset tree

Root Asset 7-BM (tier = Unit, facility_code = aps); sub-systems nest below by parent_id. The families in bold are loose design-intent names that are not in the catalog yet (they render as plain text); each is tagged with the open question that decides whether it is earned into the catalog or folds into an existing Family plus settings.

Asset Tier Family Notes (from the 7-BM docs)
7-BM Unit (root) bound to the APS Site, Sector 7
Source Device Beam the storage-ring source; loose source representation, never a catalog Family
StationShutterA Device Shutter 7-BM-A station shutter
Filters Device Filter water-cooled filter set, two units
Chopper Device Chopper rotary chopper, notched Cu disks, photoeye pickoff; white-beam duty-cycle reduction
WhiteBeamSlit Device Slit white-beam slits, repositioned per DMM stripe
Monochromator Device Monochromator double multilayer monochromator, 6 to 18 keV
MultilayerMirror Device Mirror single-bounce multilayer mirror, white-beam mode
FocusingMirrors Device Mirror Kirkpatrick-Baez focusing pair, focused-beam mode
SafetyShutter Device Shutter safety shutter between the hutches
TomographyRotation Device RotaryStage sample rotation; tomoScan-driven, as at 2-BM
SamplePositioning Device LinearStage sample centring and translation
EDDSlit Device Slit energy-dispersive-diffraction gauge slits
FlowController Device FlowController Sierra Smart-Trak mass-flow controllers; settable actuator
Scintillator Device Scintillator for indirect x-ray imaging
TomographyCamera Device Camera area camera via visible optics
HighSpeedCamera Device Camera high-speed movie camera (Photron Nova S16)
Photodiode Device Photodiode PIN diode for time-resolved radiography; presents the Sensor Role
EnergyDispersiveSpectrometer Device EnergyDispersiveSpectrometer germanium energy-dispersive detector; presents the Sensor Role
Timing Device TimingController two DG645 generators plus softGlue; ring-sync and top-up inhibit

Reused catalog Families (no new Family needed): Beam, Shutter, Filter, Slit, Monochromator, Mirror, RotaryStage, LinearStage, Scintillator, Camera, TimingController, and EnergyDispersiveSpectrometer (graduated once 2-ID and 7-BM shared it). The tomography path (scintillator plus visible optics plus area camera) is the same shape as 2-BM and could later compose the cross-facility Microscope Assembly. The three loose families (Chopper, FlowController, Photodiode) are bound by design intent and earned into the catalog only when a confirmed device and the naming review settle them; this mirrors how TomoWISE carried HeatAbsorber and SlipRing.

Pending confirmations

Every value below is taken from the 7-BM docs or inferred, awaiting the beamline team. Each is tracked by an open question; the answer lands in the descriptor and the row is removed.

Hutch PSS permit signals both enclosures unknown-pending-confirmation (PSS-1)
Source type after APS-U Source unknown-pending-confirmation (SRC-1)

Assertion-style questions that do not leave a value blank (the technique scope TECH-1, the hazard-workflow boundary HAZ-1, the timing-subsystem shape TIMING-1, and the sector and resource-sharing question SECTOR-1) are on Open questions without a placeholder here.
