On the Theory of Ion-Cyclotron Instabilities in Collisional Rotating Plasma

The role of collisions in the ion-cyclotron instabilities in the rotating plasma has been investigated. Collisional varieties of such instabilities at moderate collisions have been shown possible. At frequent enough collisions the total stabilization of such instabilities takes place. A survey of the contemporary state of the problem of the ion-cyclotron instabilities in rotating plasma has been given.
