Characteristics of cell-structure hadron calorimeter on the base of plastic scintillator mouldings

Design features are considered and the results of measurements of the characteristics of a full-scale hadron calorimeter with 1 m2 aperture, about 8 t in weight and the 10x10 cm cell are presented. The polysterene scintillator made by the moulding method has been used in the calorimeter. The calorimeter is aimed at measuring neutron energy in experiments with hyperon beams. The calorimeter possesses a good spatial (14 mm at 37.5 GeV energy) and energy (0.7/√E) resolution and permits to detect both charged and neutral hadrons in the wide energy range. The calorimeter is easily producible and reliable in operation. The calorimetr design permits to assemble detectors of a large aperture by joining of some modules with 1x1 m cross section
