Focal plane detectors of a Laue lens telescope for nuclear astrophysics

Gamma-ray astrophysics in the energy range of nuclear transitions (from a few hundred keV to a few MeV) has an extraordinary potential for understanding the evolving and violent Universe. In spite of the strong e orts accomplished by past and current instruments in order to perform observations in t...
