论文摘要
已经开发了两个独立的光束挡块，以改善气体充值离子离子garis-ii的光束分离。使用208pb（18o，3n）第223反应对这些补充束阻止者进行了性能评估。观察到GARIS-II焦平面处的信噪比的A160倍。
Two independent beam stoppers have been developed for improving the beam separation of the gas-filled recoil ion separator GARIS-II. Performance evaluation of these supplemental beam stoppers was performed by using the 208Pb (18O,3n)223Th reaction. A160-fold enhancement of the signal-to-noise ratio at the GARIS-II focal plane was observed.
