摘要
为了改进低能次级束逆运动学核反应角分布的测量,研制了空心的多环型半导体探测器,用来取代沿用多年的XY位置灵敏型半导体探测器.论述了多环型探测器的优越性,介绍了其制作过程和工艺,给出了已研制成功的十一环探测器的性能测试结果.
A multi-ring semiconductor detector has been developed for the measurements of the angular distributions of nuclear reactions induced by secondary ion beams in inverse kinematics. The advantages of the multi-ring detector are generally discussed and the manufacturing procedure is presented. The detector has 11 independent rings forming a φ100 mm silicon wafer with the thickness of 300 μm. Aφ7 mm hole is cut in the center in order to avoid recording the beam at 0° directly. The active area and the energy resolution of each ring are typically 450 mm2 and 32 keV in FWHM (5.156 MeV a particles), respectively. The detector is used in the angular distribution measurement of 11C(d,n)12N reaction and the performance is briefly described.
