为GSI的RISING项目开发了一个活动塞子，用于β衰变研究和射弹碎裂/裂变反应后的转换电子能谱。该系统在GSI碎片分离器（FRS）的最后焦平面上采用了六个双面硅条探测器来探测碎片的衰变及其随后的带电粒子（α，β，p）衰变。所需的能量响应范围很广（150 keV到几个GeV），可以通过使用对数计数器来实现。用~（207）Bi转换电子源测量，在电子能量为1 MeV时，能量分辨率为20 keV，探测阈值为150 keV。本文还讨论了400 AMeV ~（136）Ar ~+离子注入有源阻挡层的响应。
An active stopper for the RISING project at GSI has been developed for β-decay studies and conversion electron spectroscopy following projectile fragmentation/fission reactions. This system employs six double-sided silicon strip detectors in the final focal plane of the GSI FRagment Separator (FRS) to detect both the fragment implantations and their subsequent charged-particle (α,β, p) decays. The wide range of energy response required (150keV up to several GeVs) was covered by the use of a logarithmic preamplifier. Measurements with a207Bi conversion electron source yielded an energy resolution of 20keV at electron energies of ∼1MeV and a detection threshold of 150keV. The response to the implantation of 400AMeV136Xe ions in the active stopper is also discussed in the present paper.
