Outline of Final Research Achievements |
Development of General Anti-Particle Spectrometer (GAPS) has been carried out. GAPS is motivated to investigate the dark matter physics through unexplored highly sensitive observation of cosmic-ray antiparticles, including hitherto undiscovered antideuterons. In preparation for the Antarctic balloon flights, key technologies such as lithium-drifted silicon detectors and heat-pipe cooling system have been developed. Using their engineering models as well as the flight models, their fundamental performances have been verified at the system level. These achievements successfully concluded the GAPS preparation phase toward the Antarctic-balloon science flights.

Academic Significance and Societal Importance of the Research Achievements |
ダークマターの解明は現代の宇宙物理学・素粒子物理学における喫緊の重要課題の一つである。ダークマターの解明には多角的な研究が求められており、本研究で推進するGAPS実験計画は宇宙線反重陽子という新しい手掛かりを開拓することで他実験とは異なる視点からダークマターの正体に迫る重要な知見を提供できる。 観測実現のために開発した半導体検出器やヒートパイプ冷却システムは他の宇宙線観測実験のみならず放射線医療やエコ住宅建築など他分野にも応用可能な新規技術である。
