Polarized protons for ISABELLE
Conference

OSTI ID:6788345
Polarized proton acceleration and storage in ISABELLE (the Brookhaven 400 GeV proton collider) is possible if the injector synchrotron, the Brookhaven AGS, produces polarized beams. For polarized protons in ISABELLE, the injection energy has to be lowered to about 22 GeV, and one or two Siberian Snakes have to be installed to eliminate resonances. Magnet imperfections may still have some depolarizing effect, especially at high energies; however, if orbit errors are kept small enough, it appears that polarization can be maintained at least to 300 GeV. Either transverse or longitudinal polarization is obtainable. If polarized H ion sources with currents around 100 microamperes become available, the luminosity of ISABELLE with polarized beams is estimated to be less than an order of magnitude below that with unpolarized beams, i.e., about 10/sup 32/ cm/sup -/ sec/sup -1/.None
