A 28 GHz superconducting ECR (electron cyclotron resonance) ion source was recently developed at KBSI (Korea Basic Science Institute) to produce the high current and high charge state ions. The condition of the ion beam extracted from the ion source should be analyzed by a diagnosis tool after accelerating and focusing process. For this, we developed an ion beam diagnostic system composed of a slit, a wire scanner, a view screen and a faraday cup. The interface of the diagnostic system was designed so as to achieve stable operation of the ECR ion source. The information obtained from the diagnostic system can be used as a reference in studies of the optimum beam conditions needed to adjust the extraction parameters. The details of the diagnostic system and initial test results will be reported.

In 2009, a 28 GHz superconducting electron cyclotron resonance (ECR) ion source was developed to produce high currents, diverse heavy ion charge state for the compact heavy ion linear accelerator at KBSI (Korea Basic Science Institute). The aim of this study was to generate a high current, and fast neutrons for interacting a heavy ion with the proton target. The fabrication of the key parts, which are the superconducting magnet system with the liquid helium re-condensed cryostat, the 10 kW high-power microwave considering for optimum operation at the 28 GHz ECR Ion Source, were completed in 2013. The waveguide components were connected with a plasma chamber including a gas supply system. The plasma chamber and ion beam extraction were inserted into the warm bore of superconducting magnet. In this paper, we present the current status of the installation of an ECR ion source and report on the test results for ECR plasma ignition.
