As the third injector of the RIKEN Ring Cyclotron (RRC), RILAC2 has been constructed in order to increase the beam intensity of uranium beam at the RIKEN RI beam factory. The RILAC2 consists of a superconducting ECR ion source (SCECRIS) with an operational frequency of 28 GHz and the linac system (RFQ followed by three drift-tube linacs, DTL1, DTL2 and DTL3). The installation of DTL1, DTL2 and DTL3 started in February 2010 next to the AVF injector site. The SCECRIS, after tested in RILAC pre-injector of high voltage terminal, was installed in newly constructed small building outside of Nishina memorial building. The RFQ were installed in the spring 2010 after its operation frequency was slightly changed. The construction of beam lines (LEBT and HEBT) followed it. The construction will soon finish and the beam commissioning with a Xe beam will start at the end of 2010. It is expected that beam intensity of uranium beam will be improved much in the autumn 2011.
