Vann, R.G.L., Berk, H.L. and Soto-Chavez, A.R. (2007) Strongly driven frequency-sweeping events in plasmas. Physical Review Letters, 99 (2). 025003-4 PAGES. ISSN 1079-7114
A generic model of a kinetic plasma formed from a source and sink is presented which without instability would form a strongly unstable state due to a single mode. Instead, the resulting wave-particle resonant interaction maintains the distribution near a marginally stable state through the continual production of fast frequency-sweeping modes that sweep unidirectionally (upward in our case) throughout the energy-inverted region of the distribution function. The energy of these modes can be channeled to the background plasma through wave dissipation and, in our particular example, one quarter of the injected energy is available to be channeled.
