Techniques¶
What the modelled part of MANACA is designed to do, as intent. First cut.
A technique is a portable Catalog Method; a Practice is how a facility adapts it. MANACA runs macromolecular crystallography, reusing the same cross-facility MX Methods Diamond i03 introduced, so the Methods below render unlinked and are carried pending until a technique enters scope (TECH-1, ROBOT-1).
Macromolecular crystallography¶
MANACA sets the X-ray energy (5-20 keV) with the undulator and the monochromator, mounts a crystal on the goniometer (from the automated 48-pin sample changer), and rotates it through an oscillation while the area detector reads frames. It supports serial and room-temperature MX in addition to standard cryocooled rotation collection.
| Technique | Catalog method | Notes |
|---|---|---|
| Rotation MX data collection | mx_data_collection |
oscillation collection on the goniometer reading the area detector; reuses the i03 Method (also at FMX / AMX / MX3), not yet in the catalog (TECH-1) |
| Grid scan | grid_scan |
fast grid scan for sample location and centring on the goniometer; reuses the i03 Method; pending (TECH-1) |
| Sample exchange | sample_exchange |
the automated 48-pin changer load / centre / collect / unmount loop, modelled as a Procedure over the spine; reuses the i03 / MX3 Method; pending (ROBOT-1) |
Rotation MX needs the incident energy set by the monochromator, the goniometer and cryostream, and the area detector. Serial and room-temperature MX reuse the same chain with the sample-delivery and environment varied.
A new beamline on familiar vocabulary¶
MANACA is a further macromolecular-crystallography beamline after Diamond i03, NSLS-II FMX / AMX, and the Australian Synchrotron MX3, and Sirius's first MX beamline (its MOGNO sibling is tomography). It ties into the MX lineage CORA already models: the same goniometer / detector / cryostream anatomy, driven here through the Sirius EPICS floor and MXCuBE3. It reuses the mx_data_collection, grid_scan, and sample_exchange Methods directly (all carried pending across the MX fleet); none forces a new device family, and the 48-pin sample changer is a Procedure, not a new device.
Not modelled yet¶
The concrete acquisition recipes (the oscillation sequences and their exposures, the grid-scan centring, the sample-changer custody loop, the serial / room-temperature delivery) are not written yet; they join as the deployment approaches the point where CORA drives MANACA. Whether the MX Methods enter CORA's catalog is an owner-scope decision on Model; see Open questions for the world-facts to confirm first.
