GammaTPC: a transformational MeV-GeV gamma ray instrument concept

I will talk about GammaTPC, a new MeV-GeV gamma-ray instrument based on liquid argon time projection chamber (TPC) technology.  The MeV sky in particular is poorly measured, largely due to instrumental challenges. A transformative instrument in this energy range will enable a broad range of measurements, especially in the upcoming era of multi-messenger transient astrophysics. Core to GammaTPC is GAMPix, a new fine grained charge readout architecture that achieves low noise readout at very low power, and has other potential applications including neutrino physics. There are a few other amusing challenges to fielding a liquid noble TPC in low Earth orbit.
