Abstract for JLAB Technical Note 00-001

This note reports on the results of a study made of the improvements in momentum, position, and angular resolution gained by replacing the standard 4 mil Ti spectrometer exit window with a much thinner window (factor of ten reduction in radiation length) as used on the spectrometers in Mainz (Institut für Kernphysik, Johannes Gutenberg-Universität). Only effects of multiple scattering in the exit window, the following vertical drift chamber array with intervening layers of air, and the intrinsic resolution of the drift chambers themselves are considered. Improvements are found to be minimal.
