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

该项目利用南极洲西普尔站的甚低频无线电发射机继续进行一系列积极的实验。这些广泛的实验研究了电磁波与等离子体的相互作用，特别是波与范艾伦辐射带中的高能粒子的相互作用。Siple VLF发射机位于南极冰盖，因此长线天线有效地位于地表上方一公里以上。这允许相对较高的波传输效率。磁性共轭点在魁北克的密蒂西尼湖。这两个设施都配备了发射和修改的甚低频波的接收器以及一些其他诊断仪器。实验人员还在几个航天器上使用甚低频仪器。这些实验是为数不多的关于空间等离子体的活跃实验之一，对于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的实验室等离子体也很重要。此外，所获得的知识也适用于用于国家安全的甚低频/极低频/超低频通信系统。

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.
