The upgrade project for the RF system for the Brookhaven AGS

The AGS operates a varied program of proton, heavy ion, and polarized proton acceleration for fixed-target experiments and will soon serve as the injector of these beams into the Relativistic Heavy Ion Collider, RHIC. The new Booster synchrotron extends the range of intensities and masses that can be accelerated. The 1.5 GeV injection energy increases the space charge limit by a factor of four to more than 6 x 10/sup 13/ protons per pulse. To accommodate the increased beam current the RF system will be upgraded to provide more power and lower impedance to the beam. The flexibility of the RF system will also be enhanced by virtue of a new RF beam control system and installation of individual tuning servos for the ten RF cavities.<
