    Fast spectrometeric electronics for nerd installation
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Artemov, S. V.; Abdullaeva, Ya. S.; Karakhodzhaev, A. A.; Radyuk, G.

    Determination of the concentration profiles of the hydrogen isotopes in various materials is very actual problem now since hydrogen, if presents, rather strongly affects on physical, chemical, electrical, mechanical and other properties. In the INP AS (Uzbekistan) the specific method of hydrogen isotopes’ profiling (Neutron-induced Elastic Recoil Detection (NERD) method) has been developed. In this report the specific developed electronic modules (charge sensitive preamplifiers, linear gates and coincidence schemes) are described.

    Results of the nerd installation upgrading
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Artemov, S. V.; Abdullaeva, YA. S.; Karakhodzhaev, A. A.; Radyuk, G.

    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.
