Abstract
Strong focused electron beams produced by the magnetic field of an ECR ion source and a sequence of thin aluminum foils located in the ECR p lasma chamber were used for a precision adjustment between the geometr ic axis of the ECR plasma chamber and the magnetic field of the source . After adjustment the acting radial component of the magnetic field o n the source axis was not more than a few 10(-4)T. The presented metho d allows it to optimize the ECR ion source construction and to create suppositions for an effective injection of additional electrons in ECR plasmas to increase the electron density inside the source plasma.
