Abstract

A three-dimensional magnetic probe system has been designed and implemented at the Space Plasma Environment Research Facility (SPERF). This system has been developed to measure the magnetic field with high spatial and temporal resolution, enabling studies of fundamental processes in space physics, such as magnetic reconnection at the Earth's magnetopause, on the basis of SPERF. The system utilizes inductive components as sensors, arranged in an array and soldered onto a printed circuit board (PCB), achieving a spatial resolution of 2.5 mm. The system's electrical parameters have been measured, and its amplitude-frequency response characteristics have been simulated. The system has demonstrated good performance with response capabilities below 50 kHz. The experimental setup and results are discussed, highlighting the system's effectiveness in accurately measuring weak magnetic signals and its suitability for magnetic reconnection experiments.

摘要

一个三维磁探针系统已在空间等离子体环境研究设施（SPERF）中设计并实现。该系统旨在以高空间和时间分辨率测量磁场，从而能够在SPERF的基础上研究空间物理学中的基本过程，例如地球磁层顶的磁重联。该系统利用电感元件作为传感器，这些传感器排列成阵列并焊接到印刷电路板（PCB）上，实现了2.5毫米的空间分辨率。已测量了该系统的电气参数，并对其幅频响应特性进行了模拟。该系统在50 kHz以下的响应能力方面表现出良好的性能。讨论了实验装置和结果，突出了该系统在准确测量弱磁信号方面的有效性及其对磁重联实验的适用性。
