DESCRIPTION:Speakers: Irene ARKHANGELSKAJA (National Research Nuclear Univ
 ersity MEPhI (Moscow Engineering Physics Institute))\nThe gamma-quanta bac
 kground count rate model in the energy range from 0.1 MeV up to several Me
 V for high inclination satellites is presented. The AVS-F instrument (Ampl
 itude-Time Spectrometry of the Sun) was installed onboard the specialized 
 automatic station CORONAS-F functioning in time interval since July\, 2001
  up to December\, 2005 on the orbit with initial parameters: altitude ~500
  km\, inclination 82.5$^\\circ$. The device was intended for the solar fla
 res hard X-ray and gamma emission characteristic studies. The background c
 ount rate time profile of AVS-F instrument analysis allows concluding the 
 possibility of its approximation by 4-5 order polynomials in equatorial re
 gions of the satellite orbit\, and 1-3 order polynomials or constant in po
 lar caps. We obtain polynomial's coefficients for equatorial regions simil
 ar within errors intervals for the same geomagnetic indexes regions. The e
 xample of use of this method for gamma-emission background estimation for 
 RHESSI data corrected to registration efficiency\, detectors size and sate
 llite altitude (orbit parameters were: altitude ~600 km\, inclination 38$^
 \\circ$ in the beginning of its operation in January\, 2000) is discussed.
