This report is related to the testing performed at Drexel University of 250 R1408 PMTs. Based on this testing, 156 R1408 PMTs were chosen to be used in the inner veto of the detectors of the Double Chooz experiment.
This article gives a point of view on the studies of the muon-induced background for the underground experiments using a liquid scintillator detectors. The results obtained are in good agreement with the data, especially for the neutron yield production. This is the first time, when a study of this kind successes to get the same neutron yield as the one obtained from the experiment.
A simplified model is proposed based on the characteristics of the photomultiplier tube (PMT). The Model is compared to the available data, and it successes to reproduce the saturation profile of the PMT. The model also adds clarification about how the PMT works.
Simulations were performed with GEANT4 to study the cosmogenics Li-9 and He-8 production by the interactions of the muons and their secondary shower particles in the liquid scintillator. The photonuclear reactions seem dominate their production. Their energy dependence were deduced. The comparisons with available data show the reliability of the simulations results.
