New applications of high-voltage space tethers are analyzed in relation to the idea of an active experiment in the Earth's radiation belts. The tethers can effectively scatter the high energy particles into loss cone, providing a control of particle life time in Earth's radiation belts. The high energy particles are scattered due to the sheath layer formed around the tethers by cold plasma existing in ERB. The rigorous theory of the layer is developed, yielding the electric current collected by the tether and a potential profile which is then used for treatment of the scattering and diagnostics problems. Using the experimental data for trapped particles, the loss-fluxes of electrons and protons for different orbits are calculated. The rates of average losses per 1 km of the tether length at potential φp =1MV are 1.8 · 1014 s-1 for protons and 1.4 · 1017 s-1 for electrons at altitude H=2000 km, 2.5 · 1020 s-1 and 1.5 · 1016 s-1 respectively at altitude H=10000 km. The above high-voltage tethered satellite system (HVTSS) can be used for precipitation of charged particles from man-made radiation belts and development of new active experiments. In future HVTSS can be used for space weather control.
