【摘要】：雷暴期間大氣電場強(qiáng)度變化及其伴隨的宇宙線粒子增長的研究,對于理解大氣電場對宇宙線次級粒子的加速機(jī)制具有極其重要的意義.2006年4月至8月期間,西藏羊八井宇宙線觀測站記錄到了20多次雷暴事件.分析了雷暴期間,ARGO實驗scaler模式下次級宇宙線計數(shù)與大氣電場之間的相關(guān)性.結(jié)果顯示,雷暴期間大氣電場劇烈變化時,多重數(shù)n=1,2的次級宇宙線計數(shù)率有明顯增長,增幅在1%～9%之間,然而n=3,n≥4的次級宇宙線計數(shù)率增長不明顯,甚至沒有增長.該結(jié)果為進(jìn)一步研究雷暴期間大氣電場對次級宇宙線的加速機(jī)制打下了基礎(chǔ).
[Abstract]:The study of the variation of atmospheric electric field intensity and the accompanying growth of cosmic ray particles during thunderstorms is of great significance in understanding the acceleration mechanism of atmospheric electric field to cosmic ray secondary particles. More than 20 thunderstorms have been recorded at the Yangbajing Cosmic Ray Observatory in Tibet. The correlation between the secondary cosmic ray count and the atmospheric electric field in the ARGO experimental scaler model during thunderstorms is analyzed. The results show that, when the atmospheric electric field changes sharply during thunderstorms, the secondary cosmic ray counting rate of the multiple number nm1k2 increases obviously by between 1% and 9%, but the secondary cosmic ray counting rate of n + 3n 鈮，
