Generation of a controlled potential profile in the plasma to develop plasma separation method

Questions of generation buffer magnetized plasma and creation of given profile of the electrostatic potential in the working volume of the separators chamber were investigated for the purposes of plasma separation spent nuclear fuel method. Experimental researches with reflective discharge in helium were carried out. Pressures were 1 and 35 mTorr, the magnetic field was up to 2.1 kG and voltages were up to 1.2 kV. Volt-current characteristics of the discharge and the potential distribution profile, obtained using the isolated probe, were measured. Helicon discharge was chosen as a source of buffer plasma. For a discharge antenna characteristics required for generating buffer plasma in a volume of 2 m³ were calculated. (paper)
