Techniques¶
What CORA would run at FXI: the Capabilities and portable Catalog Methods CORA brings, bound through an NSLS-II Practice. The function view survives equipment swaps.
FXI is a full-field transmission X-ray microscope that does fly and step tomography, mosaic tomography, radiography, and XANES / spectro-tomography. These are the same techniques the 2-BM pilot exercised, so CORA expresses each as a Catalog Method it already carries: a second tomography deployment proves the Methods are portable across facilities. (The "demonstrated by" column names the floor plan that shows FXI runs the technique today; CORA replaces that orchestration with its Conductor, see Controls.)
Imaging¶
| CORA does | Catalog Method | Demonstrated by (floor) |
|---|---|---|
| Continuous-rotation fly tomography | continuous_rotation_tomography |
position-triggered fly scan |
| Step tomography | tomography |
stop-and-shoot projections |
| Mosaic tomography | mosaic_tomography |
tiled fields for large samples |
| Radiography | tomography |
single-angle projection series (carried under the tomography family pending a dedicated Method) |
| Flat / dark acquisition | flat_field, dark_field |
reference-frame capture per scan |
Spectroscopy¶
| CORA does | Catalog Method | Demonstrated by (floor) |
|---|---|---|
| XANES imaging / spectro-tomography | tomography + beamline_energy_change |
energy-resolved imaging across an edge |
| Energy change | beamline_energy_change |
the coupled energy move (see Recipes) |
Supporting operations¶
| CORA does | Catalog Method | Demonstrated by (floor) |
|---|---|---|
| Rotation-center finding | center_alignment |
center search during reconstruction |
| Calibration-position recording | focus_alignment |
building the energy lookup table |
Reconstruction (the tomographic recon, ring removal, rotation-center search) is CORA's compute leg, conducted over the ComputePort rather than as a beamline Method; see Controls.
