雷暴电场对LHAASO观测面宇宙线次级粒子横向分布的影响
在雷暴电场的偏转作用下,宇宙线次级粒子到达探测面的位置将受到影响,其横向分布也将发生变化。本文采用Monte Carlo方法,研究雷暴期间LHAASO观测面(海拔约4400 m)宇宙线次级粒子横向分布的变化。结果表明,雷暴期间次级粒子的横向分布将变宽,其变化幅度与电场强度有关,与天顶角、原初能量也有很强的依赖关系。在–1700 V·cm<sup>–1</sup>的电场中,次级粒子横向分布的变化幅度在天顶角0°时为3.8%,天顶角50°时为34%;当原初能量约180 GeV时,次级粒子横向分布的变化幅度为9.9%,原初能量约560 TeV时,其变化幅度高达119%。本文的...
