摘要
现有高功率激光装置中瞬态磁场测量装置未考虑屏蔽性能和信号还原.为了准确地对打靶后产生的瞬态磁场进行分析,根据瞬态磁场的频率范围和特点,基于电磁感应原理,采用黄铜作为屏蔽材料,利用皮革作为绝缘材料,设计并研制了一款适用于高功率激光装置中瞬态磁场测量的传感器.频率响应达到500 MHz,完成了相应瞬态磁场的测量,为高功率激光装置的电磁干扰、电磁兼容方面研究提供了测试手段和数据支撑.
Abstract
The existing transient magnetic field measurement in high power laser devices does not consider the shielding and signal reduction.A sensor is designed and developed for transient magnetic field measurement in high power laser devices according to the frequency range and characteristics of transient magnetic field.The brass is taken as the shielding material,and the leather is taken as the insulation material.The sensor is employed to measure the transient magnetic field,and the magnetic field response is up to 500 MHz.This work provides data support for the research on electromagnetic interference and electromagnetic compatibility for high power laser device.
