摘要
在充分考虑高温等离子体脉冲磁场测量中磁场强度高、梯度分布大、辐射干扰严重和测量环境恶劣等问题的基础上,设计了一种用于高温等离子体兆高斯脉冲磁场探测的磁探针,可成功获取高温等离子体附近区域的脉冲磁场信号,为判断高温等离子体的状态及其演化过程提供测量信息。
A B-dot probe is designed for measuring strong magnetic pulse of several million gauss generated by high temperature plasmas. A full consideration is carried out when designing this B-dot probe for measuring a strong transient peak, huge gradient magnetic pulse and it can work under harsh environment. A strong magnetic pulse signal generated by high temperature plasmas is successfully captured using our B-dot probe and it can help researchers understand the status and evolution of high temperature plasmas by presenting magnetic information.
