Techniques¶
What CORA would run at TPS 07A: rotation macromolecular crystallography, each technique a Catalog Method bound through an NSRRC Practice. TPS 07A reuses the MX Methods Diamond I03 introduced, so it coins nothing new.
TPS 07A's technique, rotation MX, is the macromolecular-crystallography shape CORA already saw at i03 (and at the Australian Synchrotron MX3, and in its serial form at i24 and LCLS-MFX). The Methods render unlinked and are carried pending until the owner-scope decision (TECH-1) brings them into the catalog, exactly as at i03 and MX3.
| Technique | Catalog method | Notes |
|---|---|---|
| Rotation MX data collection | mx_data_collection |
oscillation collection on the MD3 goniometer + the EIGER2 X 16M, orchestrated through Blu-Ice/DCSS; the i03 Method, pending (TECH-1) |
| Mesh / grid scan | grid_scan |
mesh scan for crystal location / centring on the MD3, with Dozor spot-scoring (the Meshbest path); the i03 Method (TECH-1) |
| Autonomous sample exchange | sample_exchange |
the ISARA robot load / centre / collect / unmount loop, a Procedure over the spine (ROBOT-1) |
All three are recorded as pending Practices on the NSRRC Site, reusing the same Method names Diamond i03 carries.
Why the Methods are reused, not coined¶
TPS 07A brings a new Site and a new seam, not a new technique. Rotation MX, mesh-scan centring, and robot sample exchange are the i03 shapes, so TPS 07A binds the same pending Methods (mx_data_collection, grid_scan, sample_exchange) rather than coining anything; whether those Methods enter the catalog is the cross-facility owner-scope decision i03 opened (TECH-1), and TPS 07A reinforces the case at a further MX facility (after i03, NSLS-II FMX / AMX, MX3, and Sirius MANACA). The device Roles already exist (the MD3 presents Positioner via the graduated Goniometer, the EIGER2 presents Detector via Camera), so nothing new is needed in the device model either.
The autonomous sample exchange reuses the i03 / i24 / MX3 autonomous-loop shape: a Procedure over the spine threaded through Subject custody, not a new device family (ROBOT-1). The mesh-scan Dozor spot-scoring and CHiMP crystal detection are ComputePort work (an Observe / Compute leg), not beamline Methods.
The genuinely new things TPS 07A contributes are below the technique layer: a new Site (NSRRC) and the Blu-Ice/DCSS-over-EPICS orchestration seam at an MX beamline (see Controls), which the technique vocabulary rides over unchanged.
