一个名为RILAC 2的新型直线加速器注入器已在RIKEN RI束流工厂（RIBF）成功投入使用。RILAC 2能将28 GHz超导电子回旋共振离子源（SC-ECRIS）产生的质荷比（m/q）为7的重离子，如124 μ 20+和238 μ 35+，在连续波模式下加速到680 keV/u的能量。RILAC 2的主要特点是强大的SC-ECRIS;与现有的直线加速器注入器相比，提高了射频电压稳定性，射频相位稳定性和真空水平;以及尚未安装在方位变化场（AVF）回旋加速器拱顶中的紧凑设备。2010年12月21日首次实现了光束加速。在2011年进行了几次束流加速测试后，我们开始运行RILAC 2，为RIBF的实验提供束流。
A new linac injector called RILAC2 has been successfully commissioned at the RIKEN RI beam factory (RIBF). RILAC2 can accelerate very heavy ions with a mass-to-charge ratio (m/q )o f 7, such as 124 Xe 20+ and 238 U 35+ from a 28-GHz superconducting electron cyclotron resonance ion source (SC-ECRIS), up to an energy of 680 keV/u in the cw mode. The key features of RILAC2 are the powerful SC-ECRIS; improved rf voltage stability, rf phase stability, and vacuum level compared to the existing linac injector; and the compact equipment yet to be installed in the azimuthally varying field (AVF) cyclotron vault. Beam acceleration was first achieved on December 21, 2010. After conducting several beam acceleration tests in 2011, we started to operate RILAC2 to supply beams for experiments conducted at the RIBF.
