Unveiling the nature of the knee in the cosmic ray energy spectrum

Autor: He, Huihai, Zhang, Hengying, Cheng, Qinyi, Ma, Lingling, Feng, Cunfeng

The knee-like structure around 4 PeV is the most striking feature in the cosmic ray energy spectrum, whose origin remains enigmatic. We propose a novel concept of the total logarithmic mass energy spectrum to characterize the knee, taking into accoun

Layout optimization and Performance of Large Array of imaging atmospheric Cherenkov Telescope (LACT)

Autor: Zhang, Zhipeng, Yang, Ruizhi, Zhang, ShouShan, Xie, Zhen, Liu, Jiali, Yin, LiQiao, Wang, YuDong, Ma, Lingling, Cao, Zhen

Large Array of imaging atmospheric Cherenkov Telescope (LACT) is an array of 32 Cherenkov telescopes with 6-meter diameter mirrors to be constructed at the LHAASO site. In this work, we present a study on the layout optimization and performance analy

Prospects for joint reconstruction of imaging air Cherenkov Telescope array and extensive air shower array

Autor: Zhang, Zhipeng, Yang, Ruizhi, Zhang, Shoushan, Yin, Liqiao, Liu, Jiali, Wang, Yudong, Ma, Lingling, Cao, Zhen

In this paper we proposed a joint reconstruction of \gray events using both extensive air array (EAS) and Imaging air Cherenkov Telescope array (IACT). We considered eight Cherenkov telescopes to be built on the LHAASO (Large High Altitude Air Shower

Tailoring spatiotemporal wavepackets via two-dimensional space-time duality

Autor: Chen, Wei, Yu, Anzhuo, Zhou, Zhou, Ma, Lingling, Wang, Zeyu, Yang, Jiachen, Qiu, Chengwei, Lu, Yanqing

Space-time (ST) beams, ultrafast optical wavepackets with customized spatial and temporal characteristics, present a significant contrast to conventional spatial-structured light and hold the potential to revolutionize our understanding and manipulat

Measuring the attenuation length of muon number in the air shower with muon detectors of 3/4 LHAASO array

Autor: Feng, Xiaoting, Zhang, Hengying, Feng, Cunfeng, Ma, Lingling

LHAASO KM2A consists of 5915 scintillation detectors and 1188 muon detectors, and the muon detectors cover 4% area of the whole array with 30 m spacing. The muon number of air shower events, with very high energy, is investigated with the data record
