      <Description>DOK-2 uses two pairs of energetic particle telescopes. 
        Each telescope has a single, passively cooled, totally depleted, surface-barrier silicon detector. 
        One detector of each pair (1e,2e) is of 0.3 mm thick. Thin foil in front of detector absorbes protons with energies E less than 400 keV so 
        this detector measures electron spectrum in 20 - 420 keV range. The second detector (1p,2p) of 0.15 mm thick is supplied with a broom magnet, deflecting electrons up to 1500 keV . It measures spectrum of ions (protons) in 20-850 keV range. 
        Full aperture angles and geometric factors of electron telescopes are of 27° and 0.066. 
        For proton telescopes these values are 12.7° and 0.015. Particle flux angular distribution is measured using spacecraft rotation with a ~2 min 
        period around the axis directed to the Sun (the angle ) and mechanical scanning of the second telescope pair in a plane containing the rotation 
        axis (the angle). So 3-dimensional particle distribution function is measured during each 2 min rotation period. 
        About seven full scanning cycles are carried out for every rotation. The first detector pair (1e,1p) is fixed in the antisolar direction. 
        Moving detector pair (2e,2p) can either scan from 45° to 180° (to a Sun direction) or stay in one of 4 positions: 45, 90, 135 and 180°.
