Booster:

The Booster is a rapid cycling synchrotron about 500' in diameter. The Booster accelerates a group of protons to 8 and injects them into the Main Ring. It then accelerates and injects another group. Twelve such ``batches'' are needed to fill the Main Ring. The Booster, along with the accelerators which precede it, is shown in beam:booster.
