Instabilities Associated with an Electron Beam in the Presence of Intrinsic Alfven Waves

研究人员继续研究另一种无线电发射理论，不涉及朗缪尔波。 相反，该机制依赖于行星际介质中普遍存在的阿尔芬波。 由于电子与增强的阿尔芬波相互作用，波粒共振条件被修改，导致直接放大的辐射，而不求助于朗缪尔波或非线性过程。 具体而言，他（1）进行了系统的调查的物理参数，并确定不稳定性的特点，作为这些参数的函数;（2）扩展的稳定性分析静电朗缪尔和离子声波;（3）推广他的分析，以斜传播的电磁波;（4）完全相对论推广的理论;（5）获得信息的饱和波振幅。

The investigators continue their work on an alternative radio emission theory, involving no Langmuir waves. Instead, the mechanism relies on the pervasive existence of Alfven waves in the interplanetary medium. Resulting from electron interaction with enhanced Alfven waves, the wave-particle resonance condition is modified, leading to direct amplification of radiation without recourse to Langmuir waves or nonlinear processes. Specifically, he (1) conducts a systematic survey of physical parameters and determines the instability characteristic as a function of these parameters; (2) extends the stability analysis to electrostatic Langmuir and ion-acoustic waves; (3) generalizes his analysis to an obliquely propagating electromagnetic wave; (4) fully relativistically generalizes the theory; and (5) obtains information on the saturated wave amplitude.
