There are three sensors: a gas-discharge counter D1 of the SBM-20 series and two SSD (Si) detectors D2 and D3 of 750 micron thickness. Spacecraft memory is used for data storing; time resolution is about twenty minutes. All sensors measure flux intensity continuously. +++Publication: *.1 ++++PublicationRef: S.N.Vernov, B.A.Tverskoy, N.F.Borodin, E.V.Gorchakov, A.E.Elizarov, S.I.Ermakov, V.B.Kadobnov, N.N.Kontor, G.P.Lyubimov, I.V.Maidykovskii, T.I.Morozova, N.V.Pereslegina, I.V.Sobachkin, T.I.Stepina, V.I.Tulupov, S.A.Filippychev, and T.G.Khotilovskaya, "Measurement of proton and alpha-particle fluxes on VENERA-11 and VENERA-12 space probes", Kosmicheskie issledovaniya, 1979, v. 17, N 5, pp. 804-811 +++Publication: *.2 ++++PublicationRef: S.I.Ermakov, N.N.Kontor, G.P.Lyubimov, N.V.Pereslegina, and T.G.Khotilovskaya, "Comparison of solar proton activity in 1967 and 1969 with that in 1978 and 1979 as measured aboard "Venera-4,6,11,12" space probes", 17th Int.
