New X-ray Spectrometer on the External Proton Beam


The analytical capabilities of the upgraded beamline with the external proton beam, which provides in-air micro-PIXE analysis, were further expanded with the installation of a new PB-WDS (parallel-beam wavelength dispersive) X-ray spectrometer. The spectrometer combines polycapillary X-ray optics for efficient X-ray collection with diffraction on a flat crystal analyzer and achieves energy resolution in the eV range.  Basic design of the spectrometer, main operation characteristics, together with the results of first measurements are presented in a recent paper published in the Journal of Analytical Atomic Spectrometry.
