DESCRIPTION:Speakers: Denis Bernard (LLR\, Ecole Polytechnique & CNRS/IN2P
 3.)\ngamma-ray astronomy suffers from the sensitivity gap between the\nene
 rgy ranges for which Compton telescopes and pair telescopes are\nefficient
 . \nThis blank part of the SED of the cosmic sources that are active at\nh
 igh energy hinders the understanding of their nature. In particular\nthe p
 i0 bump that is dreamt to be signing the hadronic interactions in\nthe cos
 mic accelerators that produce the highest energy cosmic rays is\nnot easil
 y observed.\n\nWe will describe the development in progress of a thin gase
 ous active\ntarget\, a time projection chamber\, as a high performance pai
 r\ntelescope for gamma-ray astronomy and polarimetry in the MeV - GeV\nene
 rgy range. \nIn particular the characterization of a prototype in a data-t
 aking\ncampaign performed recently on the 1.7 - 74 MeV gamma-ray beam at\n
 LASTI (U. of Hyôgo) will be described.\n\nhttps://indico.icrr.u-tokyo.ac.
