    ABSTRACT: A multi-laboratory-university collaborative project involving Argonne, Brookhaven, Michigan, Rice and Yale is underway to accelerate polarized protons at the AGS. The success of the now turned off 12 GeV/c ZGS polarized beam and the design studies for the AGS made us confident of the feasibility of achieving a polarization of about 60% at 26 GeV/c with an intensity 1011 to 1012 protons/pulse. Such a beam would be a potential source of polarized protons for ISABELLE. This report gives a brief discussion of the overall project and describes the tests of a prototype of the fast pulsed ferrite quadrupole magnets which will jump the intrinsic depolarizing resonances.

    ABSTRACT: The unexpected importance of high energy spin effects and the success of the 12 GeV Argonne ZGS in jumping many intrinsic and imperfection depolarizing resonances suggests that polarized proton acceleration should be tried at higher energy. The 1977 Ann Arbor Workshop concluded that it might be possible to jump depolarizing resonances in strong focusing synchrotrons. During the past year we have evaluated the possibility of accelerating polarized protons in the Brookhaven AGS. We found that for about $2 million one could obtain a polarized ion source, fast resonance jumping magnets, and 3 polarimeters which should allow acceleration of 1011 to 1012 polarized protons to 23 GeV/c with about 70% polarization or to 26 GeV/c with about 50% polarization.
