An ionisation chamber with Frisch grids has been used for the detection of proton recoils induced by fast neutrons. The working principle of the detector is explained and the test measurements are presented. The neutron energies varied from 0.3 to 2 MeV. In order to determine the total number of proton recoils, the experiment was simulated by Monte Carlo calculations. The target thickness, neutron emission angle and corresponding kinematics, radiator thickness, N-P scattering law, energy loss of protons in the radiator foil and electronic resolution have all been considered.
