[en] Ion sources based on independent arc contracted discharge with the extraction high-temperature system are described. They are intended to obtain round or rectangul-cross section beams under continuous conditions with 0.1-0.6 A current at 0.5-6 kV accelerating voltage, at discharge current equal to 2-6 A, discharge voltage - 50-100 V, gas flowrate - 1.2-2A on conversion to single ionization of all atoms entering the discharge. Area of beam transverse section constitutes up to 300 cm³ with 10% of current density irregularity at application of plane electrodes in the extraction system. It is possible to reduce or increase by several times the area of beam transverse section at application of spherical form electrodes
