分析了α粒子束驱动磁声波沿由电子、质子和α粒子组成的温度各向异性等离子体磁场传播的不稳定性。对于典型的太阳风条件，与k⊥= 0的电磁色散关系已经得到了数值求解。发现生长速率发生在氦回旋加速器频率附近。
The instability of magnetosonic waves driven by α particle beams and propagating along the magnetic field of the plasma consisting of electrons, protons, and α particles with anisotropic temperatures has been analyzed. The electromagnetic dispersion relation with k⊥ = 0 has been solved numerically for typical solar wind conditions. The growth rate was found to occur near the helium cyclotron frequency.
