| Abstract: |
GRAMS (Gamma-Ray and AntiMatter Survey) is a new project that can simultaneously target both MeV gamma-ray observations and antimatter-based dark matter search. With a low-cost, large-scale LArTPC detector, GRAMS can have a more than an order of magnitude improved sensitivity in the poorly explored MeV energy band, which is the key to understand nucleosynthesis, including possible gamma-ray emission from neutron star mergers as gravitational wave electromagnetic counterparts. GRAMS will also be a next-generation experiment for indirect dark matter search with antimatter detection. In particular, low-energy antideuterons will provide essentially background-free dark matter signatures and GRAMS could fully explore the dark matter parameter space suggested by the recent Fermi-LAT and AMS-02 observations. The GRAMS detector technology also has the potential to expand to other fields such as nuclear medicine and homeland security. In this talk, I will present an overview of the GRAMS project, focusing on the detection concept and science goals. |
