The energy deposition on the ISIS muon target and the temperature profiles are analysed in this paper. The thermal modelling is performed using the GEANT4 Monte Carlo code. Heat deposition patterns are also simulated for alternative target geometries. Energy deposition in the collimators is also discussed.

Using Geant4 Monte-Carlo simulations the potential of the Low Energy Neutrino Astronomy (LENA) liquid scintillator detector for the investigation of a possible proton decay within the channel p → Kν is discussed. Special emphasis is given to the study of background events.

In this paper we present the results of GEANT4 simulations of the production of surface muons as a function of energy of the incident protons on a graphite target. A validation of the GEANT4 hadronic physics models has been performed by comparing the results with experimental data from the Lawrence Radiation Laboratory, United States. Considering the ISIS muon target as a reference, simulations...
