We have measured the B hadron energy distribution in Z0 decays using a new technique applied to a sample of inclusive B decays recorded in the SLD experiment at SLAC between 1996 and 1997. The upgraded CCD vertex detector is used to reconstruct B-decay vertices with high efficiency and purity, and to provide precise measurements of the kinematic quantities used in this technique. For each reconstructed B-decay vertex, the part of the B energy missing from the vertex is derived from the kinematic quantities. B vertices with low missing mass are selected to provide a very high purity sample and to obtain good energy resolution. We compare the scaled B hadron energy distribution with the predictions of several QCD and phenomenological models of heavy quark fragmention. The average scaled energy <xB> is measured to be 0.719 +/- 0.005(stat.)+/- 0.001 (unfolding)(preliminary).
