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 (Astrophysics Research and Analysis) program, which includes the detector R&D and the prototype flight in the Fall 2025 or Spring 2026.
