宇宙線望遠鏡実験用大気透明度測定装置の開発

摘要

宇宙線とは宇宙空間から地球に入射する放射線の総称である．高エネルギー宇宙線は大気中の原子核と次々に相互作用を起こして爆発的に二次粒子を作り，空気シャワーと呼ばれる現象を引き起こす．%The atmospheric transparency measurement for the Telescope Array (TA) experiment in Utah, USA is done by using LIDAR system and CLF system that use the pulse laser (355 nm). The LIDAR system observes the backscattering light of the laser, and the CLF system observes the side scattering light. The consistency of the time variation of an atmospheric transparency was confirmed into the observation method and the analysis in both systems.
