[en] Application of a small selections method for spectrometry of pulsed neutron fluxes emitted with short-living hot plasma is described. The essence of the method consists in that that from the whole flux carried out are a simple random selection of small quantities of neutrons, then energy measurement of each of them by the time-of-flight method with subsequent restoration of parameters of spectral line and plasma ion temperature. Owing to modelling of spectrometry of pulsed neutron fluxes obtained were values of the spectral line parameters depending on a selection volume. The method is realized by means of a time of flight spectrometer. It is established that for measuring plasma ion temperature of the order of 1 keV with an error not worse than 50%, it is necessary to provide 6.2 m path length at Esub(n)=2.45 MeV at that the time-of-flight spectrometer consists of 100 plastic scintillation detectors, FEhU-63 photomultiplier and electronics of 0.5 ns time resolution

[en] Scintillation one-coordinate position-sensitive γ-spectrometer making it possible to obtain information in real time mode on spatial-energy distribution of γ-emitters with energies of 0.5-5 MeV is described. Coordinate resolution by γ-quanta energy of 1836 keV constitutes 1.5 cm and energy resolution - 9.6%
