[en] The fast timing selection circuit intended for the selection of coincidences and anticoincidences of two signals (the resolving time for each of them is given independently) in the limits of the third signal period shaping of signals of time mark of moments of input signals coming, shaping of logic control signals depending on the presence of coincidences and anticoincidences is described. The facility structurally is designed in the CAMAC module and is realized on the microcircuits of the 100 series and fast-response silicon transistors

[en] Principles of construction of multidetector (MDA) and multidimensional (MDTA) for time analysis in the nanosecond range are revealed. The MDA essence is in the usage of one analog-to-digital converter (ADS) for measuring events registered by several detectors. Presented is the ADC functional diagram realizing the following possibilities: usage of one ADC for supplying several independent experiments, usage of one ADC for measuring the distribution of events genetically connected with each other, usage of additional inputs into the system for the receipt of auxiliary information for the experiment control. MDA includes the following functional units: ADC, detector number coder, device for preliminary processing of the event devices for the ADC code transformation and detector number code transformation. The MDTA scheme is presented for the case of measuring two-dimensional distributions from not less than 2 detectors. A simple principle of organization of corder number interaction and the ADC pair based on the fact that the first signal from every pair of signals is fed on one ADC and the second one - on the other ADC; but event codes with ADC are commutated depending on pair number code

[en] The logics of organization of amplitude and time ''windows'' in the spectrometer for measuring neutron spectra and γ-quanta from the n(n, n'γ) reaction is described. The specific feature of the system is assignment of amplitude ''windows'' by digital method. Principle electronic device circuits description of their performance and spectra obtained with their assistance are shown

[en] A logic device for three-dimensional space-time analysis of the (n, 2n) nuclear reaction by a time-of-flight method is described. The device is intended for receiving of signals from six neutron detectors, identification of the appearance of exactly two signals associated with one dispersion act, production of a signal of operation that allows registration, formtion of a double code of the number of pairs of detectors from which the signals are taken, and assignment of these signals to two analog-digital converters. The principal schemes of construction units and time diagrams of operation are shown

[en] A description is given of equipment used in experiments on absolute measurements of neutron radiative-capture cross sections in uranium-238 in the 10-500 keV energy range. The equipment uses a time-of-flight spectrometer on the base of the PEI EG-1 pulse accelerator. The equipment set comprises a system of detectors and input recording devices, a multichannel spectrometric system to measure the flight time in nanosecond and microsecond ranges, and logical devices for measuring amplitude spectra of pulses of a radiative-capture event detector
