The developer's by-kind index: where each CORA aggregate's ID16B content lives, why this nanoprobe deployment coins no new family, and the record of what is deliberately deferred. Design-phase scaffold.

What makes ID16B new

ID16B is CORA's third non-EPICS deployment (after ID32 and ID19) and the fleet's first KB nanoprobe with XRF. The novelty sits on two axes, both below the technique layer:

  • A second BLISS / Tango floor. ID16B confirms the ID19 seam pattern is repeatable: motion stages are BLISS axes (IcePAP racks, PI piezo scanners, etel Tango motors), the fluorescence detector is a MOSCA / FalconX Tango device, the area detectors are Lima device servers, and CORA's edge conducts over the ControlPort against that floor (CTRL-1, see Controls).
  • The first KB nanoprobe with XRF. The Kirkpatrick-Baez mirror pair focuses the beam to a nanoprobe, and an energy-dispersive fluorescence detector reads a spectrum per raster point. This device combination is new to the fleet, but every part binds an existing Family.

No new families, two reused methods

ID16B holds the vocabulary constant; that is deliberate, so the new axes (floor, nanoprobe device set) are isolated.

  • The KB mirrors bind the catalog Mirror. The Kirkpatrick-Baez focusing pair is the nanoprobe; a focusing mirror is what Mirror is (OPT-1).
  • The fluorescence detector binds the catalog EnergyDispersiveSpectrometer. ID16B's FalconX silicon-drift detector reads a per-point energy spectrum, a Sensor not a 2D Frame, the same shape as the XFM Xspress3 and the 2-ID / SRX detectors (DET-1). The optical spectrometer (QEPro / Hamamatsu) reuses the same Family (DET-2).
  • The area detectors bind the catalog Camera, which presents the Detector Role. The PCO and Zyla indirect-detection cameras for nano-tomography are thin Camera instances (DET-1).
  • The stages bind RotaryStage and LinearStage. Sample rotation (the tomo / fluo-tomo master motion), coarse positioning, and the PI piezo raster scanner (the nano-XRF mapping motion) (SAMPLE-1).
  • The optics bind existing Families. Monochromator (the Kohzu DCM), Slit (primary / secondary / sample-side), FluxMonitor (the EBV beam monitors), Shutter (the fast shutter), InsertionDevice (the U205 undulator).
  • The Methods are reused. Nano-tomography is the existing tomography Method; nano-XRF mapping is the pending scanning_fluorescence_microscopy Method (2-ID / XFM / LIX). ID16B is a further consumer of each (TECH-1, METHOD-1).

ID16B coins no new Family, nothing graduates, and the catalog is unchanged.

Deliberately not here yet

  • The sample environments (ENV-1). The config carries a cryostream, a furnace, and a xeol environment with Eurotherm / nanodac regulation. A Cryostat Family is not yet in the catalog; the sample environment is deferred to keep this cut vocabulary-neutral. It is the natural first candidate for a future cut (and a rule-of-three watch for a sample-environment Family across ID16B, the 4-ID magnet / temperature stack, and others).
  • The PSS permit signals (PSS-1). The shutter handles are known; the permit signals behind them are not in the config; carried pending, not invented.
  • Vendor models, serials, focal-spot sizes, and physical positions. Not in the config; carried confirm.
  • The simulated devices and full asset-tree scenarios. No test_id16b_*.py registers the asset tree, and no vendor Models are bound.
  • Operations and experiment views. A runbook and live experiment view for a beamline CORA does not yet drive would be invention; see the note on the index.
