Spatial cyclotron resonance of ion beams.

New Dual-type Electron Cyclotron Resonance Ion Source for a Universal Source of Synthesized Ion Beams*

A new dual-type source has been constructing on the basis of electron cyclotron resonance (ECR) plasma for producing synthesized ion beams in Osaka Univ. Magnetic field in the 1st stage consists of all permanent magnets, i.e., cylindrically comb shaped one, and that of the 2nd stage consists of a pair of mirror coil, a supplemental coil and the octupole magnets. Both stage plasmas can be indivi...

In Ion-cyclotron Resonance Heating

We determine the conditions under which the damping of the fast Alfven wave, used in the heating of tokamak plasmas, can be described by the geometrical optics approximations. Also, for these conditions, we derive an analytical formula which explicitly determines the amount of energy which is damped onto the plasma particles by the fast wave. The conditions for the validity of the geometrical o...
