RADIATION/DOSIMETRY CONTROL COMPLEX

STUDY OF RADIATION CONDITIONS IN THE INTERPLANETARY SPACE



Main scientific objectives:

  • study of radiation conditions along flight trajectories to Mars and near the planet;
  • timely forecast of the spacecraft irradiation dose;
  • dosimetric control on board the spacecraft;t
  • processes of generation and propagation of charged particles in the interplanetary space;
  • estimation of meteorite hazard to a spacecraft.


    • Complex should:
  • measure Sun's X-ray fluxes within 2 to 200 keV, estimate the energy of solar X-ray bursts;
  • determine the energy spectra and spatial distribution of charged particle fluxes within energy ranges: 0.07-1.5 MeV (for electrons), 0.05-200 MeV (for protons), 2-40 Mev/nucleon (for heavy nuclei in the charge range 2
  • determine an integral dose and its rate as well as spectra of linear losses of charged particle energy within 500 keV/ m; behind 0.1 mm, 1.0 mm, 10 mm Al protection screen,
  • measure the density of micrometeoritic particle flows velocity range 3-35 km/s; mass range 5x10-4 - to 10 -9 g, and for charge of particles from 10-14 to 10-9 C.

    • Complex includes:
  • SF-2 photon spectrometer, mass 5.0 kg, (O.B. Likin, phone: +7-095-333-3356)
  • SES-20 charged particle spectrometer, mass 5.0 kg, (E.I. Morozova, phone: +7-095-333-3356)
  • KS-18M cosmic-ray monitor, mass-3.0 kg, (N.N. Kontor, fax: +7-095-939-5034)
  • RADIUS-MD meter of absorbed radiation dose (T.R. Dachev, stilrad@bgcict.bitnet)
  • TERS equivalent dose meter, mass 1.5 kg (J.Badhwar, badhwar@sn.jsc.nasa.gov)
  • AFDP -m 2 micrometeorite flux meter (V.V. Visochkin, geohi@sovamsu.sovusa)
  • RADIUS -MI interface unit (S.A. Filipichev, fax: +7-095-939-5034).

    • Operation program: continuous operation along the Earth-to-Mars trajectory; the data capacity is 2 Mbit/day; operation near Mars should follow a special program; the data capacity is 0.2 Mbit/day.
