摘要

在充满气体的反冲分离器SHANS上实现了一种用于重同位素衰变研究的焦平面探测器系统。采用标准光源和光束内实验对系统的性能进行了描述。利用脉冲形状分析技术和数字电子学实现了光带电粒子诱导的背景的显著降低。此外，探测器系统允许测量内部转换电子的低能量阈值约100 keV。

The implementation of a focal plane detector system at the gas-filled recoil separator for the decay studies of heavy nuclei

A focal plane detector system was implemented at the gas-filled recoil separator SHANS for the decay studies of heavy isotopes. The performance of the system using standard sources and in-beam experiments was described. A significant reduction of the background induced by light-charged particles was achieved using pulse shape analysis techniques with the digital electronics. In addition, the detector system allows the measurements of internal conversion electrons with a low energy threshold of about 100 keV.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
