Mission Name: Sputnik 2The Geiger-Mueller Tubes were charged particle detectors with the scientific objectives of obtaining the cosmic ray distribution over the Earth and to consequently study the magnetic field of the Earth, and of measuring the time variation of cosmic ray processes and correlating them with processes on the Earth and in the cosmos. The instrument comprised two identical Geiger-Mueller tube counters. The tubes were 100 mm long and 18 mm in diameter, backed by solid state counting circuits. Each instrument had a mass of 2.5 kg. The sensitivity of the instruments is listed as 'consistent with 10 grams/cm squared shielding'. The instruments operated at 400 V, supplied by a semi-conducting transformer powered by a 6.5 V battery. Each instrument used 0.15 W. The instruments had a planned lifetime of 200 hours and were designed to operate at an altitude range of 350 to 700 km.
