Characterization of the ion beam formed in a low magnetic field helicon mode

Lafleur, Trevor; Charles, Christine; Boswell, Roderick

Description

An experimental characterization of the ion beam formed during a low magnetic field (<3 mT) helicon mode has been performed using a number of retarding field energy analysers, for pressures between 0.03 Pa < p0 < 0.4 Pa in argon. The low-field helicon mode is formed over a narrow magnetic field range (1 mT < B0 < 3 mT) using a single solenoid giving a strong diverging field, and is characterized by a distinct density peak. For pressures below about 0.3 Pa, an ion beam is observed in the...[Show more]
