  A low energy heavy ion beam facility is being developed at Busan Center, Korea Basic Science Institute (KBSI), since 2009. The main aim of this facility is the production of high current fast neutron for the radiography. We have developed a superconducting Electron Cyclotron Resonance Ion Source (SC-ECRIS) using 28 GHz microwave source. After a first plasma ignition, various ion beams were successfully extracted since Feb. 2015. We already assembled the Low Energy Beam Transport (LEBT) line and diagnosis system of extracted after the design study of LEBT system considering beam dynamics. By adopting a RFQ as a first stage of ion beam acceleration, the extracted beam from ECRIS will be accelerated to 500 keV/Li3+ and more accelerated up to 2.7 MeV followed by a DTL. The fabrication of RFQ is in progress that will be completed in this year. In parallel, we are designing the APF-IH type DTL for a compact and reliable linac design. In this time, I will introduce the current status of KBSI heavy ion accelerator development.

  A 28 GHz superconducting ECR ion source has been built for the KBSI heavy ion accelerator facility in the Korea Basic Science Institute (KBSI SC-ECRIS). Our main goal this facility is on the generation of the high current fast neutron by using the heavy ion interaction with light target. The KBSI SC-ECRIS has been designed for optimum operation at 28 GHz. The nominal design fields of the axial magnets are 3.6 T at injection and 2.2 T at extraction; the nominal radial design field strength at the plasma chamber wall is 2 T. The superconducting magnet system with the liquid helium re-condensing cryostat, the 10 kW high power microwave system were completed in June 2013. In August 2014, the first plasma was ignited from the SC-ECRIS. In this time, we will briefly present the design of the KBSI SC-ECR ion source and its beam analyzing system. Then, results of first beam extraction at KBSI SC-ECR ion source will be described.
