The Schwinger model, or quantum electrodynamics in 1+1 dimensions, is one of the simplest gauge theories. In this talk, I will first review a standard lattice discretization of this theory using the Kogut-Susskind Hamiltonian approach with staggered fermions. I will then present a new relation between the lattice and continuum mass parameters, and show how this relation significantly improves the continuum extrapolations of various quantities computed on the lattice.
