    Abstract

    A compact helicon source having an inner diameter of 2.5 cm with 46 cm long glass tube was investigated using a Boswell type antenna. Argon gas was fed into the glass tube from the upstream end at inner pressures, 10-40 mTorr corresponding to the mass flow rates, 0.5-2 mg/s. Two apparent jumps were observed with increasing RF power. The first jump took place at about 200 W RF input, from capacitively coupled plasma (CCP) to inductively coupled plasma (ICP), and the second jump was encountered at about 500 W RF input power from ICP to presumably the helicon mode. The maximum applied magnetic field was 800 gauss. The achieved plasma density exceeded 1013 cm-3 at the expected helicon mode. Based upon this result, a few concepts of electrodeless plasma acceleration techniques were suggested and also simulated by analyses. A preliminary experiment of the acceleration for proof-of-concept was conducted.
