Microprobe x-ray fluorescence with the use of point-focusing diffractors

A toroidal point-focusing mica crystal diffractor was used to focus monochromatic x rays from a microfocus x-ray source operated at 0.1 mA and 30 kV. The Cu Kα x-ray focal spot of 50 μm×85 μm had 1.6×104 photons/s/μm2. Microprobe x-ray fluorescence (MXRF) spectra were recorded with a Si(Li) energy d...
