RUI: Design and Development of a Cubic 4 CsI(T1) Detector Array

为了获得核聚变反应动力学的详细描述，将开发一个立方阵列的掺铊碘化铯CsI（T1）探测器。 该探测器阵列将覆盖反应周围95%的空间，并能够探测反应产物发射的带电粒子的数量、能量和类型。 该阵列将被放置在反冲质谱仪的前面，如阿贡国家实验室的碎片质量分析仪或罗切斯特大学核结构研究实验室的反冲质谱仪。 有了这样的组合探测系统，就可以对每一次核反应推断出短寿命复合核发射出的所有粒子的总数和类型。 该探测系统积累的数据将用于研究重离子聚变反应中统计衰变模型的适用性。 特别是，该研究将试图确定当由三种不同的核聚变反应形成时，激发态Dy的衰变存在哪些差异。 ***

In order to gain a detailed description of the dynamics of nuclear fusion reactions, a cubic array of thallium-doped cesium iodide CsI (T1) detectors will be developed. This detector array will cover 95% of the space surrounding the reaction and will be able to detect the number, energy, and type of charged-particles emitted by the reaction products. The array will be placed in front of a recoil mass spectrometer such as the Fragment Mass Analyzer at Argonne National Laboratory or the Recoil Mass Spectrometer at the University of Rochester's Nuclear Structure Research Laboratory. With such a combined detection system, the total number and type of all particles emitted by the short- lived compound nucleus can be inferred for each nuclear reaction. The data accumulated by this detection system will be used to investigate the applicability of statistical decay models in heavy-ion induced fusion reactions. In particular, the research will attempt to determine what differences exist in the decay of excited Dy when it is formed by three different nuclear fusion reactions. ***
