4 NASA 2001 Mars Odyssey page 4 Workshop HEND Institute for Space Research, June , 2003 Main goals of experiment BTN (on Board Telescope of Neutron): - build physics model of generation of charged and neutral particles during solar flare - constructing of Earth neutron albedo model considering altitude – longitude coordinates of SC, time of day, solar activity and Earth atmosphere’ conditions - build physics model of neutron background near ISS for different flying regimes and orientations - detecting of Gamma Ray Bursts “simultaneously” with HEND of “2001 Mars Odyssey” and other SC

5 NASA 2001 Mars Odyssey page 5 Workshop HEND Institute for Space Research, June , 2003 Main parts of BTN 1. 1.Block of detectors (“HEND”) – BTN-MD 2. 2.Block of electronic - BTN-ME 3. 3.Assembly corbel with radiators – BTN-MF

6 NASA 2001 Mars Odyssey page 6 Workshop HEND Institute for Space Research, June , 2003 Block of detectors (“HEND”) – BTN-MD: - for direct detecting of neutrons of solar flare are scattering in atmosphere; - for measuring of fluxes of epi-thermal ( ) eV, resonance (1 eV MeV) and fast (0.3-10) Mev neutrons from interactions of cosmic ray with gases of Earth atmosphere; - for direct measuring X-ray and soft gamma radiation from Sun and from space in energy range 30 KeV-10 MeV.

7 NASA 2001 Mars Odyssey page 7 Workshop HEND Institute for Space Research, June , 2003 Block of electronics – BTN-ME: Power supply and control Active providing with thermal safety of BTN-MD Command transmission Telemetry transmission on board, Temporary storage of data in case unexpected delay in transmission on Earth
