[en] Described is a converter of short time intervals into intervals of a larger duration. The converter is intended for simultaneous operation with a prompt time coder. A cable delay line determines duration of the maximum converted interval ranging from 50 up to 300 nsec. Duration conversion factor is 100. Differential non-linearity is +-1% with a channnel being 50 picoseconds wide. The converter is made with integrated circuits of K137 and K138 series

Modules of preamplifier and PM divider, amplifier-scanner of two channel unit of precise time correlation, 8-channel time coder with 0.5 ns channel width and 14-input master unit are developed to realize the suggested operating circuit

[en] The brief characteristics and description of the counting-pulse time-to-code converter with 500 MHz reference frequency are given. To reduce differential conversion nonlinearity, phasing of input start- and stop-signals with generator pulses and the method of statistical levelling of quantization step are used. At channel width of 2 ns differential conversion nonlinearity is ≤ 2.5 %. The quntization level number is 4095

[en] The article deals with a fast-acting, high-capacity counter. The first stages of the counter are built around a flip-flop circuit employing tunnel diodes and transistors. The integrated section of the circuit employs the NOR gates. The flip-flops are connected through the direct current-coupled circuit. Use is made of the fast-acting elements with emitter-coupled logic which makes it possible to insure the speediest operation of the flip-flop at a frequency of at least 70 MHz. Coupling with the flip-flops employing transistor-transistor logic is effected through a transition stage using the transistors. Resetting of the flip-flop is accomplished by one trigger pulse. The reset pulse is applied to each next flip-flop at a delay equal to the previous flip-flop operation time. Such a delay is insured by the RC-circuits. The information about the state of the flip-flops can be transferred to the pulse analyzer via buffer stages. The state of the flip-flops is visually checked through miniature glow lamps NCM-9-60 BM. The counter does not call for good shaping of input pulses with respect to amplitude and width. The maximum counting rate is 270 MHz

[en] Described is a device generating time marks which are ''tied up'' to the middle of time intervals between fronts of pulses coming to its input and at the same time it is the coincidence gate for these pulses. The device is designed for weakening the effect of time dispersion related to the passage of light through extended scintillators on the time resolution of nano-second spectrometers. The accuracy of the time mark to the middle of a time interval between input signal fronts when the delay of one of input pulses changed relatively to the second one by +-2.4 ns is +-25 ps, the circuit resolution time in coincidences is 10 ns

[en] The results of operation of a new array for detecting EAS by their Cherenkov radiation are presented. The array consists of 13 detectors containing one photo-receiver KVAZAR-370. The detectors cover uniformly the area of 240 x 240 m². The first data were obtained at the array prototype consisting of four detectors. Approximately 200 000 events were detected during 94 h operation. The energy spectrum of primary cosmic radiation in the knee region was constructed on the basis of obtained data array.The preliminary results on the dependence of the EAS Cherenkov radiation spatial distribution function on the energy in the range from 100 to 10 000 TeV are obtained

[en] The time spectrometer for the measurement of magnetic fields, appearing on the μ-mesons in magnetic matters, and for the observation of the two-frequency muonium procession in large magnetic fields, is described. The spectrometer consists of the scintillation counter system (SCS) and electron apparatus. The SCS is placed within the electromagnet, creating 0-8 kOe field, perpendicular to the muon beam. The polarized muons from accelerator are halted in the target from the investigated matter. The muon stopage in the target and escape of μ-e--decay electrons are registrated by the SCS. Under working conditions with the scintillatof of 150x150x20 mm size the spectrometer time resolution equals 320 ps, differential non-linearity at the channel width 55 ps equals +-1%

[en] A time spectrometer intended for measuring large magnetic fields, which may appear on μ-mesons, and for observing a two-frequency precession of a μ⁺-meson in strong magnetic fields is described. The spectrometer consists of a system of plastic scintillation counters and electronic measuring equipment. The scintillation counters are located in the 0-8 kOe magnetic field normal to the muon beam. The detectors are viewed by photomultipliers through 600 mm long light pipes made of organic glass. The main elements of the electronic measuring system are a coincidence-anticoincidence circuit, a pulse shaper with a follow-up threshold, and a time coder. To compensate for the pulse time spread caused by the uncertainty of place of a detected particle scintillation use is made of a ''geometry compensating'' circuit. The time resolution of the developed spectrometer is 320 ps. The differential nonlinearity constitutes +- 1% at a channel width of 55 ps
