Abstract
In this paper the description and technical characteristics of the new instrument for detection of the charged secondary component of cosmic rays named CARPET-ASTANA, designed in the Dolgoprudny Scientific Station of the P.N. Lebedev Physical Institute are presented. This instrument is installed at L. N. Gumilyov Eurasian National University (Nur-Sultan, Republic of Kazakhstan) at the end of 2015. The detectors of the CARPET-ASTANA instrument are gas-discharge counters of the STS-6 type, combined in 12 blocks of 10 counters in each. Each block has two layers. The upper counter layer has separated from the lower counter layer by an aluminum filter with a thickness of 7 mm. The results of determining the barometric coefficient for the CARPET-ASTANA instrument and analysis of the first experimental data are presented in this paper. The issue of detection accuracy is also discussed.
