  We propose a new experiment at the AGS to search for the T-violating
polarization of the muon normal to the decay plane of the K+ to mu+ pi0 nu
decay. Motivated by the need for a stronger CP violation source to account for
the baryon asymmetry of the Universe, the experiment aims to search for
T-violation beyond the Standard Model. The experiment will be performed with
in-flight decays from an intense 2 GeV/c separated K+ beam at the AGS. We
expect to analyze 10**9 events to obtain the sensitivity of delta Pt = +-
0.00013 at 1 sigma, corresponding to the sensitivity of +-0.0007 to Im(xi), an
improvement by 40 over the present limit.
