已开发出一种角度可调楔形降解器系统，用作低能放射性同位素 (RI) 束线的单能降解器，采用减速方法。该系统由一对具有二次横截面的铝质降解器组成，其重叠部分有效地充当楔形降解器；可以通过改变两个铝质降解器的相对位置来调整楔角。本文介绍了其工作原理、通过仿真评估其性能和应用范围，并进行了实验验证。
An angle-tunable wedge degrader system has been developed to be used as a monoenergetic degrader for a low-energy radioactive isotope (RI) beamline working with the slowing-down method. The system consists of a pair of aluminum degraders with quadratic cross sections, whose overlap works effectively as a wedge-type degrader; the wedge angle can be tuned by changing the relative position of the two aluminum degraders. This paper presents the operation principle, estimation of performance and application range by simulation, and the experimental validation.
