An analytic model is developed for energetic electrons interacting with plasmas. This model rigorously treats the effects of energy loss upon Coulomb interactions and reveals several important features, including the coupling of scattering and energy loss-which previous calculations had erroneously treated as independent in cases where an electron lost a significant amount (or all) of its energy. The unique transparency and generality of these calculations allows for straightforward applications when quantitatively evaluating the energy deposition of energetic electrons in various plasmas, including those in inertial confinement fusion.
建立了一个用于高能电子与等离子体相互作用的解析模型。该模型严格处理了库仑相互作用中能量损失的影响,并揭示了几个重要特征,包括散射与能量损失的耦合——在电子损失大量(或全部)能量的情况下,先前的计算错误地将其视为相互独立的。这些计算独特的透明度和通用性使得在定量评估高能电子在各种等离子体(包括惯性约束聚变中的等离子体)中的能量沉积时能够直接应用。
