    Improvement of neutron elastic recoil detection (NERD) technique for hydrogen isotope concentration depth profiling is considered. The use of 14 MeV neutrons provides a number of essential advantages which allow us analyze the deep regions of the sample. Improving of analytical characteristics of the method is achieved by decreasing, as much as possible, of the gamma and charged particles background in the measured energy spectra. To decrease the false coincidences count rate and worsening of energy resolution we turned down traditional fast - slow arrangement of the spectrometer and used fast branch of the electronics down to the last spectrometric amplifier that produces the spectrometric signal for ADC.
