Diamagnetic instability of cyclotron waves in plasma
Abstract
The existence of a diamagnetic effect is demonstrated for the first time by mathematical modeling of a magnetoactive plasma. The modulation instability of the pumping wave associated with the diamagnetic effect is investigated. Spontaneous focusing and compression increments are obtained. Numerical experiments are described in which the development of diamagnetic instability is investigated in detail. The theoretical estimates of the increments are compared with the numerical values, and the analytical relationships between the number and depth of magnetic holes and pumping intensity are verified. The analytical results agree well with the theory.
