摘要

gram(伽马射线和反物质调查)是一个气球/卫星任务，将是第一个以MeV伽马射线观测和反物质为基础的间接暗物质搜索为目标的LArTPC(液态氩时间投影室)探测器。与以前的任务相比，具有成本效益的大规模LArTPC, GRAMS可以广泛提高对MeV伽马射线和反核的灵敏度。GRAMS最近被选为NASA APRA-2022(天体物理研究与分析)项目

The GRAMS (Gamma-Ray and AntiMatter Survey) Project

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
