Phys. Rev. ST Accel. Beams 4, 084001 (2001) [10 pages]Method for enlarging the dynamic aperture of accelerator lattices
Weishi Wan * and John R. Cary Received 27 July 1999; revised 30 May 2001; published 20 August 2001 A method for finding four-dimensional symplectic maps with an enlarged nearly integrable region is described. The method relies on solving for parameter values at which the linear stability factors of the fixed points (periodic orbits) of the map have the values corresponding to integer island tunes. This method is applied to accelerator lattices in order to increase dynamic aperture. The result shows a significant increase of the dynamic aperture after correction. ©2001 The American Physical Society
