RF plasma generation in the chamber with the conducting walls

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.
