Since 1999, a new injector for the k132 cyclotron at ISL-Berlin has been operated successfully. The new machine consists of an ECR-source on a high voltage platform and an RFQ accelerator of novel 2-stage-design. Beams are injected radially into the cyclotron at an energy level of 90 to 360 keV per nucleon, at a charge to mass ratio of 1/8 to 1/5. We report on operation experience and hardware improvements.
