球形正比计数器，最近开发的，允许仪器具有良好的能量分辨率和低能量阈值的大目标质量。超低能量的结果显示在这里，导致低至25 eV的能量阈值和单电子检测灵敏度。基准结果是由于碳荧光而在270 eV处观察到良好分辨的峰，这对于这种大质量检测器是独特的性能。这个非常有前途的功能可以满足从暗物质探测到低能中微子搜索等许多具有挑战性的项目的需求。本研究的详细信息见参考文献[1]。
The Spherical Proportional Counter, recently developed, allows to instrument large target masses with good energy resolution and low energy threshold. Ultra low energy results are shown here, leading to an energy threshold as low as 25 eV and a single electron detection sensitivity. The bench mark result is the observation of a well resolved peak at 270 eV due to carbon fluorescence, which is a unique performance for such large massive detector. This very promising feature can fulfill the demands of many challenging projects from dark matter detection to low energy neutrino searches. Details of this study are given in reference [1].
