Outline of Final Research Achievements

Development of General Anti-Particle Spectrometer, GAPS, has been carried out. GAPS is motivated to investigate the early-universe physics discipline, such as dark-matter physics, through unexplored highly sensitive observation of cosmic-ray antiparticles including undiscovered antideuterons.
To boost the GAPS project toward its Antarctic balloon flights, designs of both whole payload and subsystems were improved and optimized. To make the system more robust and efficient, a novel thermal engineering technique of the oscillating heat pipe was applied to the cooling system of the GAPS detectors. The instrument designs were upgraded, too. As the result, key technologies and essential knowledges to realize GAPS were successfully achieved.
