Abstract

The matching problem for a low energy transport system in a charged particle accelerator is approached using the extremum seeking method for non-model based optimization and adaptive control. The beam dynamics used for numerical simulations are given by the KV (Kapchinsky-Vladimirsky) envelope equations. Extremum seeking is employed for the lens tuning in both a matching and a periodic channel. Numerical simulations illustrate the effectiveness of this approach.
