Two external ion sources are used for nuclear physics experiments at the Karlsruhe fixed frequency cyclotron, an ECRIS for Li+++ ions and a polarized atomic beam source. The output of the Li+++ ion source have been increased considerably since it is operated with two stages and the heating of the discharge tube has been improved. In the first stage the 2ωCE mode is used. In order to increase the intensity and to improve the beam quality of the polarized atomic beam source the electron beam (EB) ionizer of this source will be replaced by an ECR ionizer. First tests of such a new ionizer have been performed successfully in cooperation with the PSI.
