Description
I will describe GammaTPC, a proposed new LArTPC MeV gamma ray instrument concept. The MeV gamma ray sky is essentially unexplored due to the challenge of measuring multiple Compton scatters over a large detector volume. A TPC with low Z material has significant advantages for this measurement, and enables a relatively inexpensive detector with large mass and thus high sensitivity in the current era of sharply reduced costs of launching mass to space. A novel ultra low power, fine-grained charge readout is needed to match or exceed the imaging capabilities of currently proposed missions based on Si (or Ge) strip technology. Key developments are also needed for space deployment.
