Abstract

The Tunka-Grande experiment is a scintillation array with about 0.5 km ^2 2 sensitive area at Tunka Valley, Siberia, for measuring charged particles and muons in extensive air showers (EASs). Tunka-Grande is optimized for cosmic ray studies in the energy range 10 PeV to about 1 EeV, where exploring the composition is of fundamental importance for understanding the transition from galactic to extragalactic origin of cosmic rays. This paper attempts to provide a synopsis of the current results of the experiment. In particular, the reconstruction of the all-particle energy spectrum in the range of 10 PeV to 1 EeV based on experimental data from four observation seasons is presented.

Tunka-Grande闪烁阵列:当前结果

Tunka- grande实验是一个位于西伯利亚Tunka山谷的闪烁阵列，其敏感区域约为0.5 km ^ 22，用于测量大面积空气阵雨(EASs)中的带电粒子和介子。Tunka-Grande最适合研究能量范围在10 PeV到1 EeV的宇宙射线，在这个能量范围内探索宇宙射线的组成对于理解宇宙射线从银河系起源到星系外起源的转变至关重要。本文试图对目前的实验结果作一个概述。特别是基于4个观测季节的实验数据，重建了10 ~ 1 EeV范围内的全粒子能谱。
