Abstract:
In order to extend the direct observation of high-energy cosmic rays up to the PeVregion,
highly performing calorimeters with large geometrical acceptance and high energy resolution are
required. Within the constraint of the total mass of the apparatus, crucial for a space mission,
the calorimeters must be optimized with respect to their geometrical acceptance, granularity and
absorption depth. CaloCube is a homogeneous calorimeter with cubic geometry, to maximise the
acceptance being sensitive to particles from every direction in space; granularity is obtained by
relying on small cubic scintillating crystals as active elements. Different scintillating materials have
been studied. The crystal sizes and spacing among them have been optimized with respect to the
energy resolution. A prototype, based on CsI(Tl) cubic crystals, has been constructed and tested
with particle beams. Some results of tests with different beams at CERN are presented
