摘要
建立了一套用于暗物质WIMPs粒子直接探测研究的低本底、低能量阈高纯锗探测器 ,探测器质量为5g ,能量阈可以达到 10 0eV .基于标准模型的最小超对称性扩展理论 (MSSM) ,讨论了该探测器可能研究的超对称参数空间 .研究结果表明 ,在WIMPs较小质量区域 。
An HPGe detector has been constructed for the direct detection of Weakly Interactive Massive Particles(WIMPs).The supersymmetric parameter space for WIMPs detection using this HPGe detector which has 100eV low energy threshold and 5g mass has been explored based on the so called Minimal Supersymmetric extension of the Standard Model(MSSM).The result shows that it will be possible to provide the most stringent upper bounds of WIMP nucleus spin independent cross section at the lower WIMPs mass region.
