  The prototype of the hadron calorimeter module consisting of 66
scintillator/lead layers with the 15x15 cm^2 cross section and 5 nuclear
interaction lengths has been designed and produced for the zero degree
calorimeter of the BM@N experiment. The prototype has been tested with high
energy muon beam of the U-70 accelerator at IHEP. The results of the beam test
for different types of photo multipliers and light guides are presented. The
results of the Monte-Carlo simulation of the calorimeter response and energy
resolution are presented for the 2-16 GeV protons.
