最著名的相干射电辐射机制之一是电子回旋脉塞不稳定性。在这篇文章中，我们将证明，电子回旋脉泽发射是直接与特定类型的带电粒子加速和空间和实验室等离子体中的传播。这些包括电子环分布，马蹄形或新月形的电子分布函数。行星和恒星磁层是马蹄形或新月形电子分布的例子，天体物理冲击产生环形电子分布函数。在实验室中，每当电子束传播到一个较强的磁场区域时，就会产生马蹄形或新月形的分布。（© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
One of the best known coherent radio emission mechanisms is the electron cyclotron maser instability. In this article we will demonstrate that electron cyclotron maser emission is directly associated with particular types of charged particle acceleration and propagation in space and laboratory plasmas. These include electron ring distributions, horseshoe or crescent shaped electron distribution functions. Planetary and stellarmagnetospheres are examples of where horseshoe or crescent shaped electron distributions can be found and astrophysical shocks produce ring shaped electron distribution functions. In the laboratory horseshoe or crescent shaped distributions are produced whenever an electron beam propagates into a stronger magnetic field region. (© 2004 WILEY‐VCH Verlag GmbH & Co.
