GammaTPC
Next-generation gamma ray detection satellite
Our Mission
GammaTPC aims to revolutionize MeV gamma-ray astronomy by bridging the observational gaps in this crucial energy regime. Our cutting-edge Liquid Argon Time Projection Chamber offers unmatched effective area, sensitivity, and spatial resolution. GammaTPC will explore extreme cosmic phenomena—from supernova remnants and neutron star mergers to dark matter signatures—helping unlock the next era of astrophysical discoveries.

A gamma ray enters the Liquid Argon TPC and Compton-scatters off an electron. The recoil electron ionises the argon, drift electrons are collected by the GAMPix pixel anode, and the original photon direction is reconstructed — all in a single event.
