Model

The developer's by-kind index: where each CORA aggregate's I13-1 content lives, why coherent imaging coins no new family, and the record of what is deliberately deferred. Design-phase scaffold.

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

What makes I13-1 new

I13-1 is CORA's first coherent lensless-imaging beamline. The fleet has tomography, XRF microprobe, and a hard X-ray nanoprobe (HXN), but no ptychography or coherent diffraction imaging (CDI). Ptychography raster-scans a coherent illumination across overlapping points on the sample and records a far-field coherent-diffraction pattern at each point; the real-space image is reconstructed downstream from the diffraction stack. That is the novelty, and it is an acquisition shape plus a reconstruction, a new Capability deferred as a pending Method (TECH-1), not a new device class.

No new families

The scout that surfaced I13-1 anticipated a new "coherent imaging" device family. That is the wrong axis: coherent imaging is a Method, not a device. The devices the technique needs are a sample-scanning stage and an area detector, both of which the catalog already covers, so I13-1 coins no new Family and changes nothing in the catalog:

  • The piezo sample-scanning stage binds the catalog LinearStage. The ptychography raster is its operative motion; the fixed-angle lab-frame variant (BL13J-MO-PI-02:FIXANG:) is a setting on the same stage, not a separate device class (SAMPLE-1).
  • The Merlin photon-counting detector and the side viewing camera bind the catalog Camera. The Merlin records the far-field coherent-diffraction pattern (the science detector); the side camera is for alignment (DET-1).
  • The machine state binds the loose StorageRing (MACHINE-1).

The coherent imaging itself is the ptychography Method, the fleet's first, carried pending (TECH-1).

Deliberately not here yet

  • The shared I13 source and optics (SRC-1, OPT-1). The dodal i13_1 module exposes only the coherence-branch endstation; the undulator, monochromator, mirrors, and slits are upstream and not in the module, so they are deferred, not invented. This is the same partial-first-cut posture as I20-1.
  • The ptychography Method and the reconstruction. Whether ptychography / CDI enters CORA's catalog as a Capability / Method is an owner decision; the Practice renders unlinked, pending (TECH-1). The image reconstruction from the diffraction stack is ComputePort work, not a beamline device.
  • The simulated devices and full asset-tree scenarios. No test_i13_1_*.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.
