  The Gamma-Ray and AntiMatter Survey (GRAMS) project is a proposed
next-generation balloon/satellite mission targeting both MeV gamma-ray
observations and antimatter-based dark matter searches. A cost-effective,
large-scale Liquid Argon Time Projection Chamber (LArTPC) detector technology
will allow GRAMS to have a significantly improved sensitivity to MeV gamma rays
while extensively probing dark matter parameter space via antimatter
measurements.
