Neutron TOF Experiments Using Transparent Rubber Sheet Type Neutron Detector with Dispersed Small Pieces of LiCaAlF6 Scintillator

We developed a new type of neutron detector using a transparent rubber sheet in which small pieces of Eu doped LiCaAlF6 scintillator are dispersed. We demonstrate that the proposed rubber sheet type neutron detector can show a clear neutron absorption peak in the pulse height spectrum and can easily eliminate gamma-ray events with pulse height discrimination in neutron TOF experiments at the 45 MeV electron Linac facility of Hokkaido University.
