ABSTRACT

The booster for the AHF at Los Alamos is a 9-period, rapid-cycling synchrotron with circumference of 261 m, operating between 157 MeV and 4 GeV, injecting into a 50 GeV Main Ring. It is filled from an H-linac, and is designed to operate at 5 Hz with an average intensity in excess of 2x I 012 protons per pulse. Lattice functions for this machine are shown in Fig. I. Fig. 2 shows a 3-D layout of the ring.
