A Multi-gap Resistive Plate Chamber (MRPC) equipped with heaters to improve the counting rate capability was designed for the BM@N experiment in Dubna. The measurements were performed using a muon beam at IHEP U-70 accelerator in Protvino. The MRPC at 40$^0$C tolerates counting rate up to 6 kHz/cm$^2$ with time resolution ~65 ps and efficiency ~95\% which complies with the conditions of the experiment.
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.
