SRX¶
Submicron-resolution X-ray spectroscopy at NSLS-II, beamline 5-ID: a multi-technique hard X-ray microprobe (XRF mapping, XANES, XRF-tomography, diffraction, imaging). This page describes how CORA would model and run SRX; the model is reverse-engineered from public configuration, not yet confirmed by SRX staff.
| Property | Value |
|---|---|
| Asset | SRX (root Asset, tier = Unit, parent_id = None) |
| Facility | NSLS-II (bound via facility_code = "nsls2", FacilityKind = Site) |
| Sector | Sector 5 (PV namespace XF:05ID*) |
| Institution | Brookhaven National Laboratory (context; not modeled as an Asset or Facility) |
| Status | Reverse-engineered from public config (design-phase scaffold) |
| Source | IVU21 in-vacuum undulator (SR:C5-ID:G1{IVU21:1}) |
How CORA would land on SRX
These pages describe how CORA would model, govern, and conduct SRX, the fourth NSLS-II beamline after FXI, HXN, and BMM. They are not a survey of the beamline's current software. The hardware facts (devices, EPICS PVs, axes) are read from public NSLS-II open source (the NSLS2/srx-profile-collection profile collection) and verified against it; vendor part numbers and physical positions are not in it, so they, and every read value, are carried confirm until SRX staff verify them (Open questions). This is a design-phase scaffold: the descriptor and these docs, with scenarios deferred.
The defining shape: many techniques, one instrument¶
The earlier deployments each anchor one technique family (FXI full-field imaging, HXN scanning ptychography, BMM spectroscopy). SRX is the first that runs several on one beamline: scanning XRF mapping, XANES, XRF-tomography, diffraction (via pixel detectors), and full-field imaging, across a micro endstation and a KB-focused nano endstation. The value to CORA is breadth, exercising the multi-Capability-per-beamline shape, and reuse: SRX introduces no new device Family, binding the ones the earlier NSLS-II beamlines and the catalog already carry.
The beamline¶
Along the beam, in order:
- Source: the IVU21 undulator and the optics hutch (
5-ID-A), rendered as the generated source-stage device walk: the high-heat-load monochromator, the focusing mirror, and the white/pink-beam and secondary-source slits. - Sample: the KB nanofocus optics and the nano-endstation sample stack rastered through the focused spot, with the attenuators and sample-environment thermal control.
- Detector: the detector set that selects the technique, the fluorescence spectrometer (XRF/XANES), the pixel detectors (diffraction), the imaging camera, and the flux counters.
Cutting across all three:
- Controls: the Zebra position-capture trigger for fly XRF mapping and the motion controllers.
The cross-cutting reference view is the Inventory.
Techniques¶
Techniques: the several techniques SRX runs, each a Catalog Method bound through an NSLS-II Practice, and the multi-Capability-per-beamline shape they exercise.
Governance¶
Governance: who may act at SRX and the trust shape CORA applies; CORA brings its own per-Actor authority.
