Abstract
A monolithic polycapillary optic was coupled with a mini focus x-ray source. The convergent beam of this system was used for micro fluorescence an was compared to a rotating anode source. The fluorescence intensities obtained from identical samples have been compared. Monolithic polycapillary x-ray optics can collect x-rays from mini and micro focus sources over a large solid angle and refocus them outside of the tube envelope into a small spot several tens of microns large. The intensity gain of such a system can exceed tow orders of magnitudes. This makes it possible to obtain intensities comparable or larger than available with common high intensity rotating anode sources. The smaller size, lower cost, ease of use and immediate availability of the Oxford mini focus source, makes it an attractive option for a variety of microanalysis applications.
