Outline of Final Research Achievements

High-energy cosmic rays are observed through atmospheric air showers. To understand the fundamental processes in air showers, collider data at proton-proton collisions are widely used. This research is to prepare future experiment to measure particle production in light ion collisions at LHC. Silicon pixel sensor was combined with tungsten plates to compose a simple shower calorimeter. Showers developed in the calorimeter was successfully observed. A MC study of LHC oxygen-oxygen collisions was performed and an optimal pixel size was determined to be 2mm. Importance of this kind of detector for future experiments was explained in the report summarized by the LHC forward physics woking group.
