Abstract
GRAMS (Gamma-Ray and AntiMatter Survey) is a balloon/satellite mission that will be the first to target both MeV gamma-ray observations and antimatter-based indirect dark matter searches with a LArTPC (Liquid Argon Time Projection Chamber) detector. With a cost-effective, large-scale LArTPC, GRAMS can have extensively improved sensitivities to MeV gamma rays and antinuclei compared with previous missions. GRAMS was recently selected for the NASA APRA-2022 (Astrophysics Research and Analysis) program, which includes the detector development and the prototype flight in the Fall 2025 or Spring 2026.
