Experimental Investigation of Modulational Effects in a Magnetized Plasma.
Abstract
Pulsed microwaves of frequency 2.43 GHz with 6 ms in pulse width are launched parallel to the external magnetic field into a magnetized plasma in a mirror machine with mirror ratio of 1.27. The plasma is produced by the same microwave pulse by the method of Electron Cyclotron Resonance using hydrogen gas. When the hydrogen neutral pressure is about 2 - 3x10('-5) torr and the incident microwave power is about 150 watts, large modulations on all signals were observed and have been investigated. We attribute the modulation to a relaxation type oscillation in the plasma.
