The expedition. -was organized by the Siberian Institute of Terrestrial Magnetism, ono~.- sphere and Radio Wave Propagation. The vessel returned to Leningrad on. 10 Mare —Kbout 40 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 strato~ . spheric balloons. About 40,000 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 -.erossed azimuthal telescope which made it possible to use 35 channels for registry of the soft and hard components from different directions at Se “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 distribution of cosmic ray intensity. It was an IGY monitor with 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’ radium-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.

_CPYRGHT |. Cosmic Ray Expedition In accordance with the recommendations of the Section on Cosmic Rays .. .... "and Radiation Belts of the Soviet Geophysical Committee and the Scientific co “ Gouncil on the Problem "Cosmic Rays," an integrated expedition was organized . for investigating the distribution of the intensity of cosmic rays during. the period of low solar activity over the territory of the USSR. The es _. -expedition was organized by the Siberian Institute of Terrestrial Magne -*-tisgm, Tonosphere and Radio Wave pagation Siber an Department éadeny Joo of Sciences USSR; the scientific director was Doctor of Physical and | Mathematical Sciences L. I. Dorman. i The first stage of the expedition took place during July-October “1965 along the profile Irkutsk-Krasnoyarsk (along the Yenisei), Dudinka -~ (Aretic Ocean), Murmansk-Kandalaksha (White Sea — Baltic Canal; Volga, “Don, Sea of Azov), Thi ligi-Ashkhabad-Kushka-Tashkent-Alma~Ata-Novosibirsk~ os Irkutsk. The apparatus included two neutron monitors with different geome- >) try; a complex counter telescope with 24 different channels for the registry » "of the Al-meson, electron-photon and general components. Measurements in the | “ gtratosphere were made with balloons. Investigations of the distribution OF cutofé rigidities dmportant for study of the world picture were made; ~ “eorrelation coefficients between primary and different secondary components Of cosmic rays were found (including for oblique telescopes); total multi- ..plicities were found for the generation of secondary particles of different types. oa The second stage in the expedition for investigating the distribution a “of cosmic ray intensity over the. territory of the USSR, organized by the , Siberian Institute of Terrestrial Magnetism, Ionosphere and Radio Wave - Propagation Siberian Department Academy of Sciences USSR under the direction ' .8£ Doctor of Physical and Mathematical Sciences L. I. 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 sactions. The monitor was designed for work in the Arctic at low temperatures and also _amdexr conditions. close to tropical, a high temperature and humidity. A . series of tests made it possible to find measures for improving operation ‘sof the monitor. In addition, measurements were made with a telescope and _. .° measurements were made in the stratosphere with balloons. These data were _ '“ cs prtocessed for finding the spatial distribution of cosmic rays, the correla- ‘tion coefficients and total multiplicities of generation of secondary parti- .- The total results of the expedition will be published in the Rezul’= “,. tary Issledovaniy po Mezhdunarodnym Geofizicheskim Proyektam (Results of | * Investigations Under International Geophysical Projects), a series published. ~ - by the committee.
