We present an analytic method for the calibration of X-ray fluorescence spectra collected using cylindrically bent crystal analyzers in any arrangement with respect to the sample and detector. Cylindrically bent analyzers are often used in the von Ha

An X-ray emission spectrometer that can detect the sulfur Kα emission lines with large throughput and a high energy resolution is presented. The instrument is based on a large d-spacing perfect Bragg analyzer that diffracts the sulfur Kα emission a

We present a high energy resolution x-ray spectrometer for the tender x-ray regime (1.6–5.0 keV) that was designed and operated at Stanford Synchrotron Radiation Lightsource. The instrument is developed on a Rowland geometry (500 mm of radius) usin

Wavelength-dispersive spectroscopy (WDS) finds applications in X-ray facilities. Since the energy resolution depends on the spatial or angular resolution of detection in the dispersion direction, the detectors of choice are typically strip detectors

A new confocal PIXE set-up at the Jožef Stefan Institute in Ljubljana was recently designed and built. It consists of a silicon-drift detector, a specially designed polycapillary lens and a snout-alignment interface for precise positioning. It allow
