摘要:

极端宇宙空间观测站-望远镜阵列(EUSO-TA)是一个地面实验,是JEM-EUSO(联合实验任务-极端宇宙空间观测站)的一部分,专门用于与望远镜阵列(TA)实验并行观测超高能宇宙射线(UHECR)。EUSO-TA操作的主要目标是测试硬件和校准EUSO探测器,以获得宇宙射线观测的最佳性能。除了中央激光设施(CLF)、移动激光器和紫外二极管等人工源校准外,来自恒星的天然信号也可用作校准源。这项工作提出了EUSO-TA探测器的校准结果。讨论了大气和探测器参数对恒星观测的影响。考虑到恒星是具有已知紫外辐射参数的点源,估计了来自恒星的信号幅度以及EUSO-TA探测器的点扩散函数。这种独特的校准方法可用于JEM-EUSO计划的未来任务,如EUSO-SPB2(超压气球)。

英文摘要:

The Extreme Universe Space Observatory-Telescope Array (EUSO-TA) is a ground-based experiment, part of the JEM-EUSO (Joint Experiment Missions -- Extreme Universe Space Observatory) dedicated to the observation of Ultra High Energy Cosmic Rays (UHECRs) in parallel with the Telescope Array (TA) experiment. The main goal of EUSO-TA operations is to test the hardware and calibrate the EUSO detector to obtain optimal performance for cosmic ray observations. Apart from the artificial source calibration such as the Central Laser Facility (CLF), mobile lasers and UV diodes, natural signals from stars can be also used as a calibration source. This work presents the results of the calibration of the EUSO-TA detector. The influence of the atmosphere and of the detector parameters on star observations are discussed. Considering, stars as point-like sources with well known UV emission parameters, signal amplitudes from stars as well as the EUSO-TA detector point spread function were estimated. This unique calibration method could be used in future missions of the JEM-EUSO program such as EUSO-SPB2 (Super-Pressure Balloon).
