我们开发了一种简单的一维闪烁光纤探测器（SFD），用于在碎片分离器的动量色散焦平面中标记高能（几百 MeV/u）和高强度（每秒约 106 个粒子，pps）光束（Z≤10）离子。该 SFD 由 60 排横截面为 2 毫米见方的闪烁纤维组成。光束强度在 103 至 106pps 之间时，检测效率保持恒定，通过倾斜注入离子可实现 100% 的位置检测效率。位置分辨率小于1mm（rms）。此外，SFD 被证明可以有效识别鸡尾酒光束中的粒子。这些结果表明，闪烁纤维的应用被发现是标记轻放射性离子束的最合适的方法之一。
We have developed a simple one-dimensional scintillating fiber detector (SFD) for momentum tagging high-energy (a few hundred MeV per u) and high-intensity (∼106particles per second, pps) beams of light (Z≤10) ions in the momentum-dispersive focal plane of a fragment separator. This SFD consists of 60 rows of scintillating fibers that have 2mm square cross-sections. The detection efficiency is constant for beam intensities between 103and 106pps and a position detection efficiency of 100% is achieved by injecting ions obliquely. The position resolution is less than 1mm (rms). In addition, the SFD is demonstrated to be effective for identifying particles in cocktail beams. These results show that the application of scintillating fibers is found to be one of the most suitable methods to tag the light radioactive ion beams.
