Abstract：
At RIKEN, three ECR ion sources (10GHz ECRIS, 18GHz ECRIS and liquid He-free SC-ECRIS) are operated as external ion sources of heavy ion accelerators. In the last year, multi-charged uranium ion beam was produced from 18GHz ECRIS by using UF₆ and the ²³⁸U ion was successfully accelerated by the accelerator complex which consists of the RFQ linear accelerator, RIKEN heavy ion linear accelerator (RILAC) and RIKEN ring cyclotron accelerator (RRC). The typical beam intensity of ²³⁸U¹⁴⁺ was about 2pμA on faraday cup after analysing magnet. ⁷⁰Zn beam was still supplied for the new super-heavy element search experiment with insertion method. Intense beam of ⁷⁰Zn¹⁶⁺ was produced for long term (～43 days) without vacuum break and remarkably low material consumption rate (～100μgr/h). We already supplied Zn beam longer than 200 days for this experiment. ⁴⁸Ca ion was also produced by insertion method using ⁴⁸CaO rod for the nuclear physics experiment. In this contribution, we will present ion source parameter and techniques for production of each of the metal ions.
