AHF booster tracking with SIMPSONS

The booster lattice for the Advanced Hydrotest Facility at Los Alamos was tracked in 3-D with the program SIMPSONS, using the full symplectic lattice from TEAPOT, the full set of magnet and misalignment errors, and full spacecharge effects. The only corrections included were a rough closed-orbit correction and chromaticity correction. The lattice was tracked for an entire booster cycle, from multi-turn injection through acceleration to the top energy of 4 GeV, approximately 99,000 turns. An initial injection intensity of 4 x 10(12), injected in 25 turns, resulted in a final intensity of 3.2 x 10(12) at 4 GeV. Results of the tracking, including emittance growth, particle loss, and particle tune distributions are presented.
