Numerical Simulation and Interpretation of the Results of Lead Ion Production in the ECR Ion Source at CERN

A new library of the computer codes for the mathematical simulation of heavy ion production in the ECR ion source is presented. These codes are based on the equations of model of ion confinement and losses in ECR ion sources. The ECR4 developed at GANIL is now used for lead ion production for the accelerator complex at CERN. An ion pulse with a current of up to 100 emA of Pb27+ has been regularly injected into the linac since May 1994. The results of numerical simulation with these computer codes and interpretation of experimental data of lead ion production in the ECR source at CERN are presented.
