Abstract
A gas Time Projection Chamber can be used for gamma-ray astronomy with excellent angular-precision and sensitivity to faint sources, and for polarimetry, through the measurement of photon conversion to pairs. We present the expected performance in simulations and the recent development of a demonstrator for tests in a polarized photon beam.
