Fast-electron current oscillations in the case of parametric instability in a plasma layer
Batanov G.M., Silin V.A.
We investigate experimentally the oscillations of the current of fast electrons produced when a microwave is incident on a plasma layer. The increased excess above threshold changes the oscillation frequency from 22 to 4 MHz. The phenomenon is explained on the basis of the premises of the nonstationary theory of Langmuir turbulence.
