雷暴期间大气电场(AEF)变化与EAS粒子增加的一致研究对于认识AEF引起的次级宇宙线粒子加速具有重要意义。2006年4月至8月，羊八井宇宙线观测站频繁记录到雷暴。本文分析了雷暴期间AEF剧烈变化时AEF与定标器模式计数率的相关性。结果表明，4个通道的计数率对雷暴剧烈变化的反馈不同。 AEF,表明它们的能量和大部分成分是不同的。总的来说,n = 1,2通道的计数率有较大的增加,从1%到9%不等,而n = 3,n≥4通道的计数率变化较小或没有明显变化。这些初步结果对于进一步研究次级宇宙线的加速机制具有重要意义。
Coincident study on the Atmospheric Electric Field(AEF) change and EAS particle increase during thunderstorm is very important in understanding the acceleration of secondary cosmic rays particle caused by AEF.From April to August,2006,thunderstorms were frequently recorded at Yangbajing Cosmic Ray Observatory.This work analyzed the correlation between AEF and scaler mode counting rate during thunderstorm when the AEF has violent change.The results revealed that the counting rate of four channels had different feedback on the violent change of AEF,which showed that their energy and most components were different.In general,counting rate in channels of n = 1,2 are found to have large increase varying from 1%to 9%,while there was less or no significant changes for channels of n = 3,n≥4.These preliminary results were very important to further study of the acceleration mechanism of secondary cosmic rays.
