Neutron monitors (NM) at the stations Barentsburg (arch. Spitzbergen), Apatity (Murmansk reg.) and Baksan (Northern Caucasus) have new rapid recording system. New amplifier-discriminators developed in Polar Geophysical Institute were set. Also detecting tubes of NM were tested and calibrated with help of a weight magnitude analyzer. NMs have been equipped with a rapid registration system. The system records time of each pulse coming with 1 microsecond accuracy. With help of special processing of the data it is possible to detect, separate and investigate different fast phenomena or transform the data to various forms. For example, the "large dead time" mode now realized via soft processing against hardware earlier. It is possible to get "a posteriori" NM data with any time resolution too. It is used universal time and one can look at the NM count data with the same accuracy – 1 mcs.
