Hope College Physics Department Research Experiences for Undergraduates Summer 2010 Project Summary

The Large multi-Institutional Scintillator Array (LISA) was constructed in the Summer of 2010. LISA will be used to detect neutrons in the range of 0-100 MeV at the National Superconducting Cyclotron Laboratory (NSCL) in combination with the Modular Neutron Array (MoNA) and Sweeper dipole superconducting magnet. With only MoNA, there is low detection efficiency when decay energy is greater than 1.5 MeV and one of the improvements that LISA will grant is more efficient detection of neutrons from decays of greater energies, allowing new physics to be explored. LISA modules consist of a photomultiplier tube (PMT) and voltage divider assembly to both ends of 2 meter organic plastic scintillator acrylic bars. Nine different institutions each constructed sixteen bars, resulting in a total of 144 bars that together make up LISA. Undergraduates at each of these institutions will be conducting small scale experiments with their bars before shipping them to the NSCL in January.
