| Outline of Final Research Achievements |
The purpose of this study is research and development of a low cost and simple fluorescence telescope. Costs of ultra-high energy cosmic ray measurement become very high due to large-scale observatory, thus development of a low cost telescope is a matter of great urgency. The detection efficiency of the telescope is estimated by monte-carol simulation. We make the simple telescope which consists of a fresnel lens and a photomultiplier tube. We tested the telescope by observing a pseudo light source of which wavelength range is same as fluorescence light emitted from cosmic ray air showers. We succeeded to observe the light source by the telescope.
