AHF Booster Tracking with SIMPSONS


Abstract

The booster lattice for the AHF project at Los Alamos was tracked with the program SIMPSONS, in 3-D, using the full, symplectic lattice from TEAPOT, and incorporates the full set of magnet and misalignment errors, as well as full space-charge 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 100,000 turns. An initial injection intensity of 4´1012, injected in 25 turns, resulted in a final intensity of 3.2´1012 at 4 GeV. Results of the tracking, including emittance growth, particle loss, and particle tune distributions are presented.
