Extract

A new, purely growing instability has been found for a bi-Maxwellian plasma in a uniform magnetic field. Instability exists for β;11 = 4βnkT11/B2 > O.591 when Tboxhu;= 0, and ions are neglected. The growth rate is near the electron gyro frequency (or v/c the plasma frequency), and the polarization is almost electrostatic for almost perpendicular propagation. The instability is obtainable only from the complete dispersion relation.
