Abstract
Nonlinear optics effect of the beam extracted from ECR ion source is studied. Hollow beam formation due to aberrations of einzel lens is examined both numerically and analytically. Description of beam intensity redistribution due to nonlinear focusing field is given. The analytical relationship between the initial and the final beam distribution in the extraction region is derived
