摘要
介绍北京组新近提出的“CaF2 (Eu) +液闪”复合WIMP探测器的设计特点 .通过对探测器单元内部光收集效率的研究 ,初步确定了复合探测器的设计结构 .另外 ,对探测器内部放射性杂质衰变在复合探测器单元中形成的本底情况进行模拟 ,结果表明了复合探测器具有良好的排除本底的能力 .
The characters of a kind of new detector, 'CaF 2(Eu)+liquid scintillator' mixed WIMP detector, which is proposed by Beijing Group, are introduced. The preliminary design of the structure of this detector has been made, by studying its optical collection efficiency with simulation. In addition, it shows that the mixed detector would be good at excluding the backgrounds, which are produced by the decays of the radioactive contamination inside the detector.
