- Abstract
- The purpose of the Long–Baseline Neutrino Experiment is to make measurements of neutrino oscillations. The stopped muon monitors are one part of the experiment, and are designed to measure absolute flux and composition of the tertiary muon beam. The detectors operate by detecting µ+ decay in an interior water volume, and 12B decay produced by µ− capture on a graphite shell. The design of the stopped muon monitors is simulated with a Monte Carlo software package called Geant 4. The detector’s response to µ+, µ−, 12B, as well as fast and thermal neutron backgrounds are reviewed and analysed. The inability of the stopped muon monitor to detect most 12B decays, as well as the overlap in signal of neutron interactions and 12B decay, require design modifications. The graphite shell is removed and should be exchanged for a neutron shielding material, while the water volume should be replaced with mineral oil. A scintillating veto is also included to identify events which originate, and are fully contained by the mineral oil. Follow-up simulations indicate that the 12B signal is significantly improved and the scintillating veto may be able to identify fully contained events.
