Abstract

This work is devoted to study of inductively coupled RF discharge within a metal chamber with a diameter of about 1 m and a length of about 2 m in argon gas (RF frequency is 5.28 MHz). The spatial distributions of electron temperature and density depending on the magnetic induction (from 0 to 0.2 T), plasma-forming gas pressure (0.1 − 10 mTorr) and RF power absorbed in the plasma are presented. For fixed gas pressure (6 mTorr) electron temperature decrease with increasing of magnetic field was found.

  • Plasma separation method, proposed in [1] for spent nuclear fuel and radioactive wastes reprocessing, can to work in practice at about 1 m typical size of plasma volume, 0.1 − 0.2 T magnetic induction and about 1kkkk electrical potential

  • The paper is devoted to experiments with plasma generation in the presence of magnetic field in the volume limited by conductive walls
