Abstract :
The possibility of using the scattering targets for forming and extraction beam in the modern circular accelerators is considered in paper. Is shown that the minimum losses of particles will be by use of targets from heavy elements such as tungsten. The optimum sizes of a target, its displacement from septum and frequency of the betatron oscillations are determined. The analytical and numerical accounts show, that at a beam extraction of energy 70 GeV from U70 and 600 GeV from U600 is possible to reach an efficiency ~70% and ~90% accordingly
