Abstract
The paper presents the results of experiments designed to test a new two-parameter measurement system. RFNC – VNIITF has created this system to improve its experimental capabilities in nuclear physics research. The system is intended for measurement of neutron and gamma radiation spectral characteristics in the source-target-detector based experimental setup. The experiments were carried out with the time-of-flight method and the amplitude analysis technique. The work was performed with several radiation sources including cobalt-60 (Co-60), ionization chamber with the layer of Cf-252, and the NG-12I neutron generator as a 14 MeV neutron source. For detection, plastic and stilbene scintillators, and high-purity Ge semiconductor detectors with the relative detection efficiency of 50 % and 10 % were used. In these experiments, the registration time range was between 0 and 900 ns. The two-parameter measurement system allowed for implementing the following modes of operation: two-channel coincidence, time stamp release, and external trigger. The paper describes the experimental setup and the measurement results. The obtained results show that with the two-parameter system different types of detectors can be used to carry out measurements over a wide range of time and energy.
