LArGO (Liquid Argon Gamma-ray Observatory) consists of a new design for a g-ray telescope, which exploits the idea of using a Liquid Argon Time Projection Chamber (LAr-TPC) as trackerconverter.

Abstract
LArGO (Liquid Argon Gamma-ray Observatory) consists of a new design for a g-ray telescope, which exploits the idea of using a Liquid Argon Time Projection Chamber (LAr-TPC) as trackerconverter. Particle tracking in LAr-TPC can efficiently starts since the primary photon vertex. Indeed, while in the present space telescopes the incident photon converts in a tungsten foil, which is a passive material, in a LAr-TPC this conversion happens in LAr itself, which is fully active. In this proceeding is described a plausible design for the tracker-converter detector which fulfills the constraints on conversion efficiency, angular resolution, and wide field of view. It is demonstrated how this design can provide an unprecedented angular resolution for a g-ray telescope, leading to a significant improvement in sensitivity and most important disclosing the possibility to detect the polarization of γ-ray emission.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
