spectrometer
High resolution elastic scattering channel is intended for non-destructive quantitativedetermination of hydrogen and its depth distribution in the sample material by recoil nucleimethodmethod.The main advantagesThe vacuum in the scattering chamber is 10-7 Pa, that makes contamination of samplesimpossible during the experiment. The limit of detection of hydrogen is about 10 ppm. Itimpossible during the experiment. The limit of detection of hydrogen is about 10 ppm. Itallows 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 whenusing standard silicon surface-barrier detector.
