RIKEN RI束流工厂(RIBF)已经建造了一台用于RI束流实验的大容量多粒子能谱仪武士。它主要是为运动学上完整的实验而设计的，例如通过检测重碎片和抛射速度核子的重合来对奇异核中的粒子非结合态进行不变质谱学。该系统由超导偶极磁体、束线探测器、重碎片探测器、中子探测器和质子探测器组成。武士光谱仪于2012年3月投入使用，对于高达2.4GeV/c的RI光束，获得了约1/1500的刚性分辨率。(C)2013年由Elsevier B.V.发表。
A large-acceptance multiparticle spectrometer SAMURAI has been constructed at the RIKEN RI Beam Factory (RIBF) for RI beam experiments. It was designed primarily for kinematically complete experiments such as the invariant-mass spectroscopy of particle-unbound states in exotic nuclei, by detecting heavy fragments and projectile-rapidity nucleons in coincidence. The system consists of a superconducting dipole magnet, beam line detectors, heavy fragment detectors, neutron detectors, and proton detectors. The SAMURAI spectrometer was commissioned in March 2012, and a rigidity resolution of about 1/1500 was obtained for RI beams up to 2.4 GeV/c. (C) 2013 Published by Elsevier B.V.
