为了改进GARIS-II充气反冲离子分离器的束流分离，研制了两个独立的束流阻挡装置。利用208Ph(18O，3n)223Th反应研究了这些辅助束流阻塞器的性能。观察到GARIS-II焦平面的信噪比增加了160倍。
Two independent beam stoppers have been developed for improving the beam separation of the gas-filled recoil ion separator GARIS-II. Performance of these supplemental beam stoppers was investigated by using the 208 Pb (18 O, 3 n) 223 Th reaction. A160-fold enhancement of the signal-to-noise ratio at the GARIS-II focal plane was observed.
