自2009年3月以来，世界上第一个利用FFAG同步加速器加速的高能质子束产生的散裂中子的ADSR实验已经在库里开始。在这些实验中，探测到了表明由外源引起的中子倍增的瞬发中子和延迟中子。库里用于ADSR研究的加速器复合体由三个FFAG质子环组成。它以30赫兹的重复频率向位于库卡反应堆堆芯建造的次临界核燃料系统前面的W靶发射100 MeV质子束。将介绍该设施的现状以及ADSR系统和高强度脉冲散裂中子源的未来计划，这些系统和高强度脉冲散裂中子源将在库里现有的FFAG综合体上新增加一台700 MeV的FFAG同步加速器。
World’s first ADSR experiments which use spallation neutrons produced by high energy proton beams accelerated by the FFAG synchrotron has started since March 2009 at KURRI. In these experiments, the prompt and delayed neutrons which indicate neutron multiplication caused by external source have been detected. The accelerator complex for ADSR study in KURRI consists of three FFAG proton rings. It delivers the 100 MeV proton beam to the W target located in front of the sub-critical nuclear fuel system constructed in the reactor core of KUCA at 30 Hz repetition rate. Current status of the facility and the future plans of ADSR system and high intensity pulsed spallation neutron source which employ a newly added 700 MeV FFAG synchrotron to the existing FFAG complex in KURRI will be presented.
