Abstract:

The program studyed instabilities resulting from energetic ion beams streaming across a magnetic field, or other non-equilibrium features, such as temperature anisotropy or a loss cone distribution function, and to calculating th emission of radiation at the fundamental and harmonics of the cyclotron frequency and at the second harmonic of the plasma frequency. The program has five tasks. 1. Effect of electron thermal anisotropy on the kinetic cross-field streaming instability. 2. Applications of kinetic cross-field streaming instabilities to laboratory experiments. 3. Electromagnetic electron-cyclotron instability excited by energetic electrons with a loss-cone distribution. 4. Induced emission of electromagnetic radiation near the second harmonic of the plasma frequency, and 5. calculation of spontaneous cyclotron emissivity using the complete relativistic resonance condition.
