Status and Plans for the Daejeon Ion Accelerator Complex at KAERI

The Daejeon ion accelerator complex (DIAC) is being built at the Korea atomic energy research institute (KAERI) in order to fulfill an increasing demand for heavy ion beam facilities for various applications including biological and nanomaterial research. Based on linacs of the Tokai radioactive ion accelerator complex (TRIAC) given from the high energy accelerator research organization (KEK), Japan, the dedicated accelerators in the DIAC are designed to produce stable heavy ion beams with energies up to 1 MeV/u and beam currents up to 300 µA. In this article, status, plans, and some preliminary test results for the DIAC construction are presented and discussed. At present the full-power test of the IH2-4 linacs is limited by the multipacting. Based on the understanding of the multipacting characteristics, full-power test of all IH linacs will be finished soon. After that, full-power test of the RFQ linacs, the radiation shielding analysis, the beam tuning will be done until the end of this year
