There are six sensors: a gas-discharge counter D1 of the STS-5 series, and a Cherenkov counter D2 (30x30 mm plexiglas), and four SSD (Si) detectors: D3, D5 of ~30 micron thickness and D4, D6 of ~400 micron thickness. Spacecraft memory is used for data storing; time resolution is about four hours. All sensors measure flux intensity continuously. +++Publication: *.1 ++++PublicationRef: S.N.Vernov, B.A.Tverskoy, V.A.Yakovlev, E.V.Gorchakov, P.P.Ignatiev, G.P.Lyubimov, O.A.Marchenko, T.E.Shvidkovskaya, N.N.Kontor, T.I.Morozova, A.G.Nikolaev, Yu.A.Rosental, E.A.Chuchkov, I.V.Getselev, L.V.Onischenko, and B.I.Tkachenko, "Charged particle fluxes in the vicinity of Mars", Kosmicheskie issledovaniya, 1974, v. 12, N 2, pp. 252-263 +++Publication: *.2 ++++PublicationRef: N.N.Kontor, G.P.Lyubimov, P.P.Ignatiev, E.V.Gorchakov, and T.E.Shvidkovskaya, "Solar Proton Anisotropy in September 1973", Space Research XVI-Akademie-Verlag, Berlin, 1976, pp. 769-774 +++Publication: *.3 ++++PublicationRef: E.V.Gorchakov, P.P.Ignatiev, V.A.Iozenas, T.E.Shvidkovskaya, V.A.Yakovlev, I.V.Getselev, B.I.Tkachenko, N.N.Kontor, N.G.Galatchyev, and G.P.Lyubimov, "Measurement of rigid cosmic rays in September 1973 on space probes MARS-4, MARS-5, MARS-7", Kosmicheskie issledovaniya, 1976, v. 14, N 1, pp. 65-72 +++AcknowledgingTo: TASPD SINP MSU +++DataSet: *.1 ++++ID: M5 ++++StartDate: 73/07/26 ++++StopDate: 74/02/08 ++++TimeResolution: 4 hours ++++ApproxVolume: 15 kB ++++DataSupportContact: Dr. Nickolay N.
