  This white paper describes LAr1-ND and the compelling physics it brings first
in Phase 1 and next towards the full LAr1 program. In addition, LAr1-ND serves
as a key step in the development toward large-scale LArTPC detectors. Its
development goals will encompass testing existing and possibly innovative
designs for LBNE while at the same time providing a training ground for teams
working towards LBNE combining timely neutrino physics with experience in
detector development.
