CONSEQUENCES OF THE PLASMA-MASER INSTABILITY IN MAGNETIZED PLASMA

The total momentum and energy conservation relations for the plasma-ma ser interaction among the resonant, nonresonant modes, and the electro ns are satisfied for magnetized plasma. The Manley-Rowe relation in it s original Form is violated because the resonant electrons carry nonli near momentum and energy. The plasma-maser satisfies the generalized M anley-Rowe relation which includes the effective action from resonant electrons in addition to the original one from waves. It is shown that the plasma-maser effect works if there are Onsager symmetry breaking factors such as temperature anisotropy due to external magnetic field, inhomogeneity due to density gradient. The generation mechanism of th e electromagnetic radiation is studied based on the plasma-maser inter action among the electrostatic lower hybrid turbulences, accelerated e lectrons and extraordinary mode radiation. The theory agrees with the most striking and new features of the observation of the auroral kilom etric radiation (AKR) in that the AKR bursts are observed at frequenci es well above the local electron gyrofrequency.
