- Аннотация: A high speed recording system operated on a neutron monitor (NM) is developed at the Laboratory of Cosmic Rays, Polar Geophysical Institute (PGI). The system records the time a neutron arrives to the NM, in a file, the precision of recording being of 1 μs. The number of the tube is also recorded. The data thus contain the exact time and the place of each of billions of pulses arrived. The recording system is placed on a number of stations, such as Apatity, Barentsburg, Moscow, Neitrino (the Northern Caucasus). The system is used to study the phenomenon of multiplicity on NM, as well as other effects of short-time occurrence. In data handling by pulse selection from a given set of tubes, there is a possibility to modernize a conventional NM to get a device of a different design, due to the actual task. That is, it is possible to get a modernized neutron monitor of a specified design without its stop, disassembling and transformation. A number of electronic neutron monitors have been developed to study the multiplicity events. These monitors differed in different distance between the tubes (with 1-15 tubes omissible). The spacing function for multiplicity events has been obtained. The spacing function has been analyzed to show that great values multiplicities are the result of atmospheric hadron showers, while moderate values multiplicities are of a conventional origin. All the pulses entering the events, are checked if there are any disturbances in order to filter the false multiplicity events off the periodic interference.
