摘要:

CYGNO项目的目标是使用具有光学读出的气态TPC来探测低能量阈值和方向性的暗物质和太阳中微子。CYGNO演示器将由1立方米的体积组成,在大气压下填充He:CF 4气体混合物。光学读出与高粒度CMOS传感器,结合快速光探测器,将提供一个详细的重建的事件拓扑结构。这将允许区分核反冲信号与背景,主要由放射性诱导的低能电子反冲表示。由于高重建效率,CYGNO将对低质量暗物质敏感,并有可能克服中微子底,这最终限制了非定向暗物质的搜索。

英文摘要:

The CYGNO project has the goal to use a gaseous TPC with optical readout to detect dark matter and solar neutrinos with low energy threshold and directionality. The CYGNO demonstrator will consist of 1 m 3 volume filled with He:CF 4 gas mixture at atmospheric pressure. Optical readout with high granularity CMOS sensors, combined with fast light detectors, will provide a detailed reconstruction of the event topology. This will allow to discriminate the nuclear recoil signal from the background, mainly represented by low energy electron recoils induced by radioactivity. Thanks to the high reconstruction efficiency, CYGNO will be sensitive to low mass dark matter, and will have the potential to overcome the neutrino floor, that ultimately limits non-directional dark matter searches.
