  Domain Wall Fermions utilize an extra space time dimension to provide a
method for restoring the regularization induced chiral symmetry breaking in
lattice vector gauge theories even at finite lattice spacing. The breaking is
restored at an exponential rate as the size of the extra dimension increases.
As a precursor to lattice QCD studies the dependence of the restoration rate to
the other parameters of the theory and, in particular, the lattice spacing is
investigated in the context of the two flavor lattice Schwinger model.
