摘要:

极端宇宙空间观测站是一个通过记录最高能量的宇宙射线在大气中产生的广泛的空气簇射来研究它们的实验。为此,将使用国际空间站日本实验舱上的一台大型高速摄像机记录这些阵雨发展的录像片段。录像片段将用于确定这些宇宙射线的能量和到达方向。这些测量的准确性取决于准确测量每个簇射的固有光度和方向。本文介绍了如何在飞行期间使用由位于大气层深处的校准闪光灯和激光器组成的全球照明系统来测试和提高这些测量的准确性。

英文摘要:

The Extreme Universe Space Observatory is an experiment to investigate the highest energy cosmic rays by recording the extensive air showers they create in the atmosphere. This will be done by recording video clips of the development of these showers using a large high-speed video camera to be located on the Japanese Experiment Module of the International Space Station. The video clips will be used to determine the energies and arrival directions of these cosmic rays. The accuracy of these measurements depends on measuring the intrinsic luminosity and the direction of each shower accurately. This paper describes how the accuracy of these measurements will be tested and improved during the mission using a global light system consisting of calibrated flash lamps and lasers located deep in the atmosphere.
