  A new injector for the RIKEN RI-Beam Factory (RIBF) has been fully commissioned since October 2011. The injector accelerates ions of m/q=6.8 up to 670 keV/u. In order to save the cost and space, a direct coupling scheme was adopted for rf coupling between the cavity and amplifier, based on an elaborate design with the Microwave Studio code. It has worked out very stably in these three months, making the uranium beam intensity higher by one order of magnitude. Moreover, it is now possible to operate the RIBF and GARIS facility for the super-heavy element synthesis independently.
