    • Abstract. Studies were made the possibilities of increasing the wave-dispersive X-ray fluorescence spectrometer analytical characteristics due to using the superfine beryllium foils 5-8 μm thick in the X-ray detector. Investigations by the example of ...
    • 2. Estimating the possibility of improving the analytical characteristics of the spectrometer
    • Thus, when beryllium foil 5 μm thick is used as an entrance window and 8 μm thick beryllium foil is used as a detector window, the recorded intensity of secondary radiation should increase by 4.2 times for sodium, 2.3 times for magnesium, 1.7 times fo...
    • Calculations show that the foil thickness reducing can significantly increase the analytic characteristics of the device when determining light elements (sodium and magnesium).
    • 3. Experimental evaluation of improving the analytical characteristics of the spectrometer using the superfine beryllium foils
