Detector¶
Detection¶
The autoranging USAXS photodiode detector, the incident and transmitted flux monitors, the counting scalers, the detector and SAXS/WAXS stages, and the pinhole SAXS and WAXS area detectors.
Enclosure: 12-ID-E.
Note
USAXS detection is point / current-integrating: the UPD photodiode reads the rocked-analyzer intensity through an autoranging Femto transimpedance amplifier across several gain decades, the science detector. It, and the I0 / I00 / I000 / TRD monitor channels and the counting scalers, reuse the catalog FluxMonitor (the BMM quad-electrometer-as-primary precedent; the gain autorange is a device-state setting, DET-1). The same instrument runs pinhole SAXS and WAXS on Pilatus area detectors, which reuse Camera.
