Letter of Intent: LAr5-A Liquid Argon Neutrino Detector for Long Baseline Neutrino Physics
Abstract
This Letter of Intent presents the case for developing a Proposal to construct a liquid argon neutrino detector with a total mass of approximately 5 kilotons. The detector can be be located in the existing and currently operating NuMI beam. The design of this detector will incorporate techniques which have been discussed for the construction of much larger scale detectors. We contend that a project of this scale is necessary to determine an optimum configuration for the detector masses required to achieve significant sensitivity to measuring CP violation in the neutrino sector. Additionally, we have investigated the physics sensitivity that could be achieved by such a detector and find it to be comparable and complementary to the NOνA experiment. Physics results from both NOνA and LAr5 will yield the best return on the investment that has been made in the NuMI facility.
