Detector¶
The detectors that make SST multi-technique: the soft-scattering CCD (RSoXS, SST-1), the hemispherical electron analyzer (HAXPES photoemission, SST-2), the microcalorimeter (NEXAFS fluorescence), the flux monitors, and the beamstop. This stage spans both branches; each device note states its branch. PVs verified against the RSoXS, HAXPES, and NEXAFS TOML manifests.
Enclosure: SST-1.
Note
Which detector is read decides the technique: the Greateyes CCD for soft X-ray scattering, the Scienta electron analyzer for photoemission, the transition-edge microcalorimeter for energy-resolved fluorescence, or the drain-current / diode channels for absorption. All reuse existing families. The retired or commented detectors (the second RSoXS Greateyes SAXS arm) are not modelled (DET-1).
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
ScatteringDetector |
Camera |
XF:07ID1-ES:1{GE:2} |
Greateyes 4k x 4k CCD area detector (the RSoXS WAXS detector); reuses Camera. A second Greateyes SAXS arm is commented out in source (DET-1). | confirm |
|
ElectronAnalyzer |
ElectronAnalyzer |
XF:07ID-ES-SES |
Scienta SES hemispherical electron analyzer (the HAXPES photoemission detector in the SST-2 tender branch; pass energy, lens mode, kinetic / excitation energy, acquisition mode, from the NSLS-II-SST/haxpes ses.py SES class). A photon-in / electron-out device that fits no photon-detector family. Binds the catalog ElectronAnalyzer family: SST-HAXPES is the SECOND sighting (n=2, the same Scienta SES type) after ESM, which GRADUATED the family into the catalog (ARPES-1). | confirm |
|
CalorimeterSpectrometer |
EnergyDispersiveSpectrometer |
XF:07ID-ES{UCAL}: |
Transition-edge-sensor (TES) microcalorimeter for energy-resolved fluorescence (NEXAFS); it resolves photon energy per event to give a spectrum, so it reuses EnergyDispersiveSpectrometer. Whether a cryogenic microcalorimeter is a per-Asset settings variant of that family (alongside the silicon-drift and germanium variants) or warrants its own Family is a question; carried as reuse for now. Its ADR cryostat (XF:07ID-ES{UCAL:ADR}) is deferred (INSITU-1). | confirm |
|
FluxMonitor |
FluxMonitor |
XF:07ID-ES1{DMR:I400-1} |
The bound PV is the RSoXS I0 photodiode (I400 electrometer). Other incident-flux channels live under separate prefixes: an Au-mesh I0 on a second I400, and the HAXPES / NEXAFS drain-current and ion-chamber channels on SR570 amplifiers into ADC buffers. Reuses FluxMonitor (graduated #353). The full channel map is pending (DIAG-1). | confirm |
|
BeamStop |
BeamStop |
XF:07ID2-ES1{BS-Ax:1}Mtr |
RSoXS motorized beamstop (BeamStopW) blocking the direct beam ahead of the CCD; a separate beamstop-diode current channel reads its intensity. Reuses BeamStop. | confirm |
|
SampleCamera |
Camera |
XF:07ID1-ES:1{Scr:4} |
On-axis sample-viewing optical camera (RSoXS; side and imager cameras serve alignment). Reuses Camera. | confirm |
