Description
Summary:A Multi Purpose Detector (MPD) is being constructed for the Heavy-Ion Collider at Dubna (NICA). One of the important components of MPD setup is an Electromagnetic Calorimeter, which will operate in the magnetic field of MPD solenoid 0.5 T and provide good energy and space resolution to detect particles in the energy range from ∼20 MeV to few GeV . For this purpose the, so-called, “shashlyk” sampling structure with the fiber readout to the silicon Multi Pixel Avalanche Photodetector is used. Serious modifications in comparison to conventional “shaslyk” calorimeter are proposed to improve the properties of device. These modifications are presented in the report along with the beam test results obtained with the MPD/NICA module prototypes.
