  We investigate the possibility to search for supersymmetry in the scattering
of protons and Compton back-scattered laser light. We evaluate the cross
sections for inelastic and elastic production of wino pairs for different
electron-proton c.m.s. energies. For $\sqrt{s}=1\ TeV$ the cross section
exceeds $1\ fb$ for $m_w<190\ GeV$.
