Abstract

We report a study on the conversion of a giant cosmic ray observatory for air shower observation to observe cosmic ray intensity variations caused by solar activity, anisotropy associated with interplanetary disturbances, and detection of sudden cosmic ray events on the earth’s surface. In this report, we use data from the surface detectors operated by the Telescope Array experiment located at 39°N, 112°W (total detector area: 2250 m2). In order to evaluate the cosmic ray intensity variations, we will compare the data with some of the corrections considered and with available world wide database such as Nagoya Muon detector and other observatories that have been in stable operation at different geographic longitudes. Finally, we will report on the intensity variations due to weather and solar activity recorded during the observation period.

用闪烁计数器对气淋观测宇宙射线强度变化的研究

本文报道了将一个巨大的宇宙射线观测站转换为气淋观测，以观测太阳活动引起的宇宙射线强度变化、与行星际扰动相关的各向异性以及探测地球表面的宇宙射线突发事件。在本报告中，我们使用望远镜阵列实验运行的表面探测器数据，该实验位于39°N, 112°W(探测器总面积:2250 m2)。为了评估宇宙射线强度的变化，我们将把数据与一些考虑过的修正进行比较，并与世界范围内可用的数据库进行比较，如名古屋μ子探测器和其他在不同地理经度上稳定运行的天文台。最后，我们将报告由于天气和太阳活动在观测期间记录的强度变化。
