论文摘要
宇宙射线是宇宙中最重要的能量转化过程之一。他们带来了有关周围宇宙，我们的星系以及最可能在最高观察到的能量的信息。在他们发现的一个多世纪之后，我们还没有关于辐射的起源，加速度和传播过程的确切模型。主要原因是，通过不同的实验获得的结果仍然存在很大的差异，这可能是由于某些仍未知的系统不确定性影响了测量结果。在本文中，我们将重点关注10 $^{15} $ eV能量范围内的银河宇宙射线，其中观察到了全粒子能量光谱中所谓的\ emph {``膝盖'}。提出并讨论了（P+HE）能量谱的测量。
Cosmic rays represent one of the most important energy transformation processes of the universe. They bring information about the surrounding universe, our galaxy, and very probably also the extragalactic space, at least at the highest observed energies. More than one century after their discovery, we have no definitive models yet about the origin, acceleration and propagation processes of the radiation. The main reason is that there are still significant discrepancies among the results obtained by different experiments, probably due to some still unknown systematic uncertainties affecting the measurements. In this paper, we will focus on the detection of galactic cosmic rays in the 10$^{15}$ eV energy range, where the so-called \emph{`knee'} in the all-particle energy spectrum is observed. The measurement of the (p+He) energy spectrum is presented and discussed.
