VLF Wave-Particle Interaction Experiments on the Magnetosphere and Ionosphere from Siple Station, Antarctica and Lake Mistissini, Quebec

该项目继续利用位于南极洲simple Station的甚低频（VLF）无线电发射机进行一系列正在进行的积极实验。这些广泛的实验研究了电磁波与等离子体的相互作用，特别是与范艾伦辐射带中高能粒子的相互作用。simple VLF发射机位于南极冰盖中，因此长线天线有效地位于地表以上一公里处。这使得波的传输效率相对较高。磁共轭点位于魁北克的密西尼湖。这两个设施都配备了用于发射和修改VLF波的接收器以及许多其他诊断仪器。实验人员还在几个航天器上使用了VLF仪器。这些实验是为数不多的活跃的空间等离子体实验之一，对理解电离层和磁层很重要。它们对于理解天体物理等离子体和聚变机器的实验室等离子体也很重要。此外，所获得的知识已应用于用于国家安全的VLF/ELF/ULF通信系统。

This project continues an on-going series of active experiments utilizing a Very Low Frequency (VLF) radio transmitter at Siple Station, Antarctica. These wide ranging experiments study the interaction of electromagnetic waves with plasmas, and in particular the interaction of waves with the energetic particles in the Van Allen radiation belts. the Siple VLF transmitter is located in the antarctic ice sheet so that the long wire antennas are effectively over a kilometer above the surface. This permits a relatively high efficiency for the transmission of the waves. The magnetically conjugate point is at Lake Mistissini, Que. Both facilities are equipped with receivers for the transmitted and modified VLF waves as well as a number of other diagnostic instruments. The experimenters also use VLF instrumentation on several spacecraft. These experiments are among the very few active experiments on space plasmas and are important for understanding the ionosphere and magnetosphere. They also are important for understanding astrophysical plasmas and laboratory plasmas for fusion machines. In addition the knowledge gained has application to VLF/ELF/ULF communications systems used for national security.
