Popis: A technique for wide-range diagnostics of the pulse form of neutrons from the ИБР-2 periodically pulsed reactor has been investigated. Organic scintillation detectors providing a wide linearity of the amplitude characteristic in the pulsed current mode and circuits controlling the detector sensitivity have been developed. A spectral sensitivity of the detectors to neutrons and γ quanta is presented. The radiation hardness of scintillators and photomultiplier tubes and the phototube stability under long-term optic loading are analyzed. An analog-to-digital wide-range recorder and its software are briefly described. The experimental results obtained using this technique with the ИБР-2 periodically pulsed reactor are given.
