Detector¶
Detectors¶
The SPECS hemispherical electron analyzer (the AP-PES detector), the Vortex and Xspress3 fluorescence detectors, the scaler and current amplifiers reading the electron-yield channels, the Au-mesh I0 monitor, and the exit-slit diagnostic camera.
Enclosure: 23-ID-2.
Note
The SPECS analyzer is the photoemission detector: it disperses photoelectrons by kinetic energy over a window set by pass energy and lens mode (a photon-in / electron-out instrument), and binds the catalog ElectronAnalyzer Family, the THIRD sighting after ESM and SST and the first non-Scienta and first ambient-pressure one (analyzer make, lens-mode set, and pass-energy range are a per-Asset settings or bound-Model difference, not a Family split; DET-1). The Vortex (silicon-drift detector + MCA) and the Xspress3 (four-channel silicon-drift) read the fluorescence yield and bind EnergyDispersiveSpectrometer (DET-2). The scaler reads the electron-yield (TEY / PEY) counting channels behind the CurrAmp:1/2/3 current amplifiers (sample drain, Au-mesh reference, photodiode), and the Au mesh is the I0 reference; both bind FluxMonitor (DET-3). The exit-slit camera is a beam-diagnostic Camera. The detection modes (TEY drain current, PEY kinetic-energy-selected electrons through the analyzer, PFY region-of-interest fluorescence) are settings, not separate devices.
