高空水切伦科夫 (HAWC) 伽马射线天文台使用 300 个水切伦科夫探测器 (WCD) 探测 TeV 能量范围内的宇宙射线和伽马射线引发的空气簇射。为了提高其在最高能量下的灵敏度,HAWC 进行了升级,在 HAWC 主阵列周围安装了由 345 个小型 WCD(支腿阵列)组成的稀疏阵列。支腿阵列将HAWC的仪器面积增加了4倍,并自2018年8月开始采集数据。已经开发出一种新的伽马射线重建方法,结合混合型粒子探测器阵列的数据来改进风淋室的重建。在这篇文章中,我们将展示使用蒙特卡罗模拟和第一个组合实验数据集对 HAWC 及其支腿阵列进行组合风淋室重建的第一个结果。
The High Altitude Water Cherenkov (HAWC) gamma-ray observatory detects cosmic- and gamma-ray initiated air showers in the TeV energy range using 300 water Cherenkov detectors (WCDs). To improve its sensitivity at the highest energies, HAWC has been upgraded with a sparse array of 345 small WCDs (outrigger array) around the HAWC main array. The outrigger array increases the instrumented area of HAWC by a factor of 4 and has started taking data since August 2018. A new gamma-ray reconstruction method has been developed to improve the reconstruction of the air showers which combines the data of mixed type particle detector arrays. In this contribution, we will show the first results of the combined air shower reconstruction of HAWC and its outrigger array using Monte Carlo simulations and the first combined experimental data set.
