A prototype flight for the GRAMS project

This grant is for the prototype balloon flight of the GRAMS (Gamma-Ray and AntiMatter Survey) Project. GRAMS mission aims to deliver unprecedented sensitivities to astrophysical observations with MeV gamma rays and indirect dark matter searches with antimatter using a cost-effective, large-scale LArTPC (Liquid Argon Time Projection Chamber) detector. We will build and optimize a small-scale detector, MiniGRAMS, and demonstrate its performance in the balloon flight scheduled in late 2025 or early 2026.
