Abstract

ALPACA (Andes Large area PArticle detector for Cosmic-ray physics and Astronomy) experiment is a collaboration project between Bolivia and Japan. It is going to be located at the Mt.Chacaltaya plateau (16° 23' S, 68° 08' W) in Bolivia, at high altitude of 4,740 m (572.4 g/cm2). As the prototype experiment of ALPACA, ALPAQUITA experiment is going to start in 2019. We evaluate the performance of ALPAQUITA with an MC simulation and give as results the detection efficiency of the ALPAQUITA AS array and the difference of muon distribution of gamma-ray induced air showers and cosmic-ray induced ones. The calculation of the sensitivity optimization for gamma-ray signals is now ongoing.
