Resonance phenomena in microwave nonmagnetized plasma source

Cyclotron resonance phenomena in a non-neutral multispecies ion plasma

Cyclotron modes of a non-neutral Mg ion plasma were studied in a long cylindrical PenningMalmberg trap. Several modes with angular dependence exp(iZ@, 12 1, are observed near the cyclotron frequencies of the various Mg ions. The I= 1 modes for the majority species are downshifted from the cyclotron frequencies, with downshifts as large as four times the diocotron frequency. These large shifts a...

Development of a long-slot microwave plasma source.

A 20 cm long 10 cm wide microwave plasma source was realized by inserting two 20 cm long 1.5 mm diameter rod antennas into the plasma. Plasma luminous distributions around the antennas were changed by magnetic field arrangement created by permanent magnets attached to the source. The distributions appeared homogeneous in one direction along the antenna when the spacing between the antenna and t...

Plasma expansion from a dielectric electron cyclotron resonance source

The boundary conditions in an electron cyclotron resonance (ECR) source have been modified to mimic the operating conditions where current-free double-layers (DLs) have been recently measured in rf helicon plasmas. The plasma is heated or generated by the ECR at 875 G inside a dielectric source tube, and expands into a grounded diffusion chamber (terminated by a glass plate) by a rapidly decrea...
