The Space Plasma Environment Research Facility (SPERF) was built in Harbin to study the three-dimensional magnetic reconnection and wave-particle interactions relevant to space physics in laboratory settings. A 2.45 GHz Electron Cyclotron Resonance (ECR) plasma source is adopted in the device to simulate the Earth's magnetosphere and achieve the scientific goals. In this paper, the design of the ECR plasma source is presented. The structures of the microwave source, the microwave transfer system, and the antenna are introduced. Additionally, the resonant surfaces are computed to predict the locations of microwave absorption. The absorption mechanisms of the microwave in the SPERF are also discussed. The discharge experiment demonstrates the utility of the ECR source in simulating the Earth's magnetosphere. The successful operation of the source indicates that the ECR discharge is a powerful tool for creating a plasma environment in a large plasma experimental device.
空间等离子体环境研究设施（SPERF）建于哈尔滨，用于在实验室环境中研究与空间物理相关的三维磁重联和波粒相互作用。该装置采用2.45 GHz电子回旋共振（ECR）等离子体源来模拟地球磁层并实现科学目标。本文介绍了ECR等离子体源的设计。介绍了微波源、微波传输系统和天线的结构。此外，还计算了共振面以预测微波吸收的位置。还讨论了微波在SPERF中的吸收机制。放电实验证明了ECR源在模拟地球磁层方面的实用性。该源的成功运行表明，ECR放电是在大型等离子体实验装置中创建等离子体环境的有力工具。
