以在神光II升级靶场使用九路激光打靶实测的电磁脉冲信号为输入源,建立平行线缆模型,研究电磁脉冲耦合电缆产生的串扰现象,揭示不同线缆间距、线缆长度受串扰的规律,以及线缆长度对串扰信号频率的影响机制。同时探讨铜箔屏蔽处理后对串扰信号的衰减。结果表明,增大平行线缆的间距有利于抑制串扰,增大线缆长度抗干扰能力减弱,谐振频率降低;屏蔽处理能有效抑制信号串扰,为高功率激光装置安全精确的开展各类物理诊断提供实验与理论支持。 相似文献

Giant electromagnetic pulses(EMPs) induced by high-power laser irradiating solid targets interfere with various experimental diagnoses and even damage equipment,so unveiling the evolution of EMPs inside the laser chamber is crucial for designing effective EMP shielding.In this work,the transmission characteristics of EMPs as a function of distances from the target chamber center(TCC) are studied using B-dot probes.The mean EMP amplitude generated by picosecond laser-target interaction reaches 56... 相似文献
