Novel ERDA and RBS facility: beamline, scattering chamber and electrostatic spectrometer 15 High resolution elastic scattering channel is intended for non-destructive quantitative determination of hydrogen and its depth distribution in the sample material by recoil nuclei method. The main advantages The vacuum in the scattering chamber is 10-7 Pa, that makes contamination of samples impossible during the experiment. The limit of detection of hydrogen is about 10 ppm. It allows the exploration of the hydrogen content in metals, where it is present in trace amounts. The relative energy spread is 1.5 10-3, which is an order of magnitude higher than when using standard silicon surface-barrier detector.
Monochromatic x-ray source on the basis of electrostatic proton accelerator 16 The main advantages The combination of high-currenth low-energy proton beam with the radiation generation chamber allowed obtaining very intense source of monochromatic X-rays with low background and high monochromaticity.
