Development of a cosmic-ray anti-particle spectrometer using exotic-atom physics for the dark-matter search

研制了通用反粒子谱仪GAPS。GAPS的目标是通过对宇宙射线反粒子（包括尚未发现的反氘核）的高灵敏度观测（或搜索）来研究暗物质之谜和其他早期宇宙物理学科。为了准备南极气球飞行，GAPS的每个子系统的原型都已经开发并通过各种测试进行了验证。2012年，使用原型GAPS有效载荷成功进行了一次工程气球飞行。因此，验证了每个GAPS子系统的基本设计和性能。

Development of General Anti-Particle Spectrometer, GAPS, has been carried out. GAPS is motivated to investigate the dark matter mystery and other early-universe physics discipline through unexplored highly sensitive observation of (or search for) cosmic-ray antiparticles including undiscovered antideuterons.In preparation for the Antarctic balloon flights, prototype of each GAPS subsystem has been developed and verified by various tests. In 2012, an engineering balloon flight was successfully carried out using a prototype GAPS payload. As a consequence, the basic design and performance of each GAPS subsystem were verified.
