Modeling o fhadron interactions in the neutron monitor 1 4 0 1Cf 3 10 ' 2 10 ‘ 1 10° 10 1 Energy, MeV Fig. 4. A typical energy spectrum of secondary neutrons resulting in interaction o f a primary neutron (100 MeV) with a lead and reached the detector layer. In Fig. 5 the calculated response function obtained with a software package GEANT4, for comparison presented together with the response function calculated in [4] with a software package FLUKA is presented. Almost on whole energy range both response functions well agree. Very similar results on the response function calculations (Fig.5) were obtained by C. Pioch et al., 2009 [5]. Though they used in the calculations with the GEANT4 package their own Physics List. Distinction in low energy range between our calculations and Clem and Dorman, 2000 [4] is connected, most likely, with distinction between cross sections used in [4] and ones in the present work. Fig. 5. Calculated response functions for the neutron monitor with 3 and 6 counter tubes (3-NM64 and 6-NM64). For calculation the standard package of physical processes GEANT4 QGSP_BERT_HP including various models for corresponding energy range was used. For comparison, the response function obtained in [4] with a software package FLUKA also is presented. 85
