Excitation of Lower Hybrid Waves in a Coaxial Type Double Plasma

抄録

Lower hybrid waves were excited in a coaxial type double plasma device, where their wave vectors were almost perpendicular to the magnetic field. The dispersion relation of the excited waves agrees fairly well with the theoretical one. The waves are effectively excited by the sinusoidal potential differences between the driver and target plasmas without insertion of metal electrodes. The method may be applicable to the plasma heating due to lower hybrid waves in high temperature plasmas.
