The (..gamma..,..pi../sup +-/) studies planned for the BNL Gamma Ray Beam Facility necessitate the detection of charged pions in the energy range 25 < T/sub pi/ < 150 MeV with a modest resolving power to match the photon beam energy resolution (27 MeV). The solid angle must be as large as possible, and the total path length must be as short as possible to minimize the losses due to pion decay. (The mean lifetime corresponds to L = 4.87 m for T/sub pi/ = 25 MeV). Finally, a means must be provided to reject pion decay products reaching the focal plane. A design for such a charged-pion spectrometer is presented. This design utilizes existing large aperture magnetic elements, and provides a momentum resolution of 0.68% at a solid angle of 50 msr, over a momentum range of 10%.
