Description
GRAMS (Gamma-Ray and AntiMatter Survey) is a next-generation
experiment that will be the first to target both MeV gamma-ray
observations and antimatter-based indirect dark matter searches. With
a cost-effective, large-scale LArTPC detector, a single long-duration
balloon (LDB) flight can have an order of magnitude improved
sensitivity to gamma rays in the poorly-explored MeV energy domain.
Additionally, GRAMS has been developed to become a next-generation
dark matter search experiment beyond the GAPS project for antimatter
survey. The antimatter measurements can provide clean dark matter
signatures while validating the possible dark matter detection
suggested in the Fermi gamma-ray observations and the AMS-02
antiproton measurements. In this talk, I will start with the overview
of the project and then focus on the detection concepts for MeV gamma
rays and antiparticles.
