摘要:

根据普遍簇射发展定理,即强子产生的广延空气簇射完全由一次能量、簇射极大值的位置和与总μ子数有关的参数描述,发展了所谓的相关曲线法,并将其应用于KASCADE资料。利用KASCADE实验测量的簇射中μ子和电子含量的相关信息,重建了初级宇宙射线的能量和质量。详细讨论了方法和结果的系统不确定度。结果表明,通过这种方法,在光谱和成分的一般趋势确实可以揭示,但在能量和质量尺度的绝对归一化需要更详细的模拟。

英文摘要:

On basis of the theorem of a universal shower development stating that a hadronically generated extensive air shower is completely described by the primary energy, the position of the shower maximum and a parameter related to the total muon number, the so-called correlation curve method is developed and applied to KASCADE data. Correlation information of the muon and electron content of showers measured by the KASCADE experiment are used for the reconstruction of energy and mass of primary cosmic rays. Systematic uncertainties of the method and the results are discussed in detail. It is shown that by this method general tendencies in spectrum and composition indeed can be revealed, but the absolute normalization in energy and mass scale requires much more detailed simulations.
