An expedition for the study of cosmic rays in the Atlantic area departed from Riga on the "Kislovodsk" on 26 November 1967.

The vessel returned to Leningrad on d R ;@d a @t o o, 10@ 10 rc@ out 0 t s f 10 are A out 0 tons of special cargo had to be carried, includ ing 10 tons of balloons with hydrogen under a pressure of 150 atm, Cosmic ray observations were made with a three-section neutron monitor,-a stabil-, ized system of 35 meson and electron-photon telescopes and with strat6- spheric balloons. About 40J.000 individual measurements@were made on shipboard and 64 balloons were launched-for measuring cosmic rays and stratospheric temperature. The charged component was registered with a crossed azimuthal telescope which made it possible to use 35 channels for registry of the soft and hard components from different directions at angles 0, 45, 55, 65, 70 and 76* to the vertical. Six additional'channels were used for checking telescope operation and determining random coinci- dences. A neutron monitor was used for studying the planetary di@tribution of cosmic ray intensity. It was an IGY monitor witl@ Simpson geometry con- sisting of three sections, each with four SNM-8 counters. The statistical error for the monitor was about +0.7 percent during 2 hours of registry. It was calibrated using a'radiuT@--beryllium neutron source. Sixty-four of 74 balloon launchings were successful (complete data for each launching are given in a table). The collected information will make it possible to find the barometric coefficients for different cosmic ray components and estimate their dependence on the energy of primary particles in the range 1-20-109 eV.

The first stage of the expedition took place during July-October 1965 along the profile Irkutsk-Krasnoyarsk (along the Yenisei), Dudinka .(Arctic Ocean), Murmansk-Kandalaksha (White Sea - Baltic Canal; Volga, Don, Sea of Azov), Thilisi-Ashkhabad-Kushka-Tashkent-Alma-Ata-Novosibirsk- Irkutsk. The apparatus included.two neutron monitors-with different geome- try; a complex counter telescope with 24 different channels for the registry of the A-meson, electron-photbn and general componej@ts. Measurements in the stratosRhere were made with balloons.

Dorman was in August- September 1966. The route covered the eastern regions of the USSR, Irkutsk,'' Ust'-Kut, then along the Lena River to Tiksi, then by the Northern Sea Route through Bering Strait into the Pacific Ocean to Vladivostok. For this stage of the investigations a special expeditionary 12-counter neutron monitor was developed; it consists of three independently operating sections. The monitor was designed for work in the Arctic at low temperatures and also conditions close to tropical, a high temperature and humidity. A series of tests made it possible to kind measures for.improving operation of were made with a telescope and -the monitor. In addition, measurements measurements were made in the stratosphere with ba lloons. These data were p@:ocessed.for finding the spatial distribution of cosmic rays'. the correla- :tion coefficients and total multiplicities of generation of secondary parti- cles'. The total results of the expedition will be published in the Rezul'@- tary Issledovaniy po Mezhdunatodnym Geofizicheskim, Proyektam (Results of Investigations Under International Geophysical Projects), a series published by the committee. They'are also to be published in the. j'ournal "Nuovo Cimento" (Italy).

The author describes the merits of a new type of dipole (CJ-5/2) in comparison with type N5 used ,earlier. The new type is a standard wind sensor for Polish meteorological rockets. A method for designing-dipoles for wind measurements is described on the basis of the new type (CJ-5/2) of dipole.
