The R&D program described in this paper focuses on an improvement of the SLAC linac designed to extract and study a 9 GeV electron beam under stringent control of energy, energy spread, emittance, optical parameters, and timing. The extraction system begins with an on-axis pulsed magnet, followed by a magnetic lattice and diagnostic equipment required for the measurement and optimization of the above beam qualities. Design, construction, and installation of this system is the first step in the development of the overall PEP-II e^± injection system. This system is required to fill 1658 bunches of 9 GeV electrons (0.99 A stored) and 3.1 GeV positrons (2.14 A stored) in two separate rings in a total of about 6 minutes from zero ring current (i.e., full-fill mode, 0 to 100%) or in about 3 minutes from 80% ring current (i.e., topping-off mode, 80 to 100%). This unprecedented rate of filling can be met by a judicious use of the SLC linac, damping rings, and positron source.
