摘要:

位于KASCADE实验中的一个大面积(128 m^2)μ子跟踪探测器(MTD)已经建成,其目的是在大于18 r.l.的条件下通过径迹测量来识别大范围空气簇射中的μ子(E_mu > 0.8 GeV)及其方向。屏蔽μ子轨道相对于簇射轴的取向用径向角和切向角表示。用三角测量法确定了μ子产生高度H_μ。利用H_mu观测到宇宙线初级粒子从轻到重的跃迁,簇射能量Eo从1-10 PeV逐渐增加。研究了15 km以上第一相互作用的μ子赝快度分布,并与蒙特卡罗模拟进行了比较。

英文摘要:

A large area (128 m^2) Muon Tracking Detector (MTD), located within the KASCADE experiment, has been built with the aim to identify muons (E_mu > 0.8 GeV) and their directions in extensive air showers by track measurements under more than 18 r.l. shielding. The orientation of the muon track with respect to the shower axis is expressed in terms of the radial- and tangential angles. By means of triangulation the muon production height H_mu is determined. By means of H_mu, a transition from light to heavy cosmic ray primary particle with increasing shower energy Eo from 1-10 PeV is observed. Muon pseudorapidity distributions for the first interactions above 15 km are studied and compared to Monte Carlo simulations.
