TI - Supply of Metallic Beams from RIKEN 18-GHz ECRIS Using Low-Temperature Oven J2 - Proc. of Heavy Ion Accelerator Technology Conference (HIAT2015), Yokohama, Japan, 7-11 September 2015 AB - In the RIKEN 18-GHz electron cyclotron resonance ion source, the practical use of low-temperature oven was achieved for the supply of metallic beams. At the RIKEN Radioisotope Beam Factory, Ca-48 beam is one of the important beams, as a primary beam to produce the secondary beam of neutron-rich medium-heavy nuclei. In order to enhance the intensity and stability of Ca-48 beam, we newly introduced a low-temperature oven and so-called "hot liner." A mixture of CaO and Al powders was placed into the crucible of the oven and heated to produce metallic calcium by a reductive reaction. We succeeded in high-intensity and stable supply of Ca-48 beam, as well as the reduction of material consumption rate. In addition, we succeeded in the supply of Zn-70 beam using the low-temperature oven. In supplying Zn-70 beam, only the ZnO powder was placed into the crucible, and the hot liner was not used. In this contribution, the configuration of low-temperature oven, the effect of the hot liner, the supply situations of Ca-48 and Zn-70 beams for a long-term experiment, and the attempts to supply other metallic beams using the low-temperature oven will be reported.
