A new 50 GeV beam capability for the end station will be developed, and spin response functions measured at higher momentum transfers to test model predictions for the momentum transfer dependence. Based on the higher energy beam, a proposal will be developed to study the flavor distribution of quarks using parity violation in deep inelastic scattering. Management and support services for other users of the SLAC End Station A facilities will be provided. ***
