Generation of neutrons produced by muons from CERN neutrino beam

Preliminary results of neutron generation by muons, produced in CERN neutrino beam with average energy 17 GeV in LVD experiment are presented for the period 2008–2011 yrs. A Monte Carlo simulation of neutrons produced by horizontal muons was performed using the Geant4 software package. The efficiency of neutron detection in the LVD was calculated. For iron-based and white spirit scintillators, the measured neutron yields prove to be Y sc = (3.6 ± 0.7) × 10−5 n/μ (g−1 cm2) and Y Fe = (23.2 ± 4.6) × 10−5 n/μ (g−1 cm2).
