论文摘要
高度像素化的固态探测器在自然放射性的识别和抑制方面具有出色的功能。我们介绍了为DAMIC实验制定的背景识别策略，该策略采用硅电荷耦合设备来寻找暗物质。 Damic证明了将每个$β$发射极的活动与$^{32} $ si，$^{238} $ u和$^{232} $ th decay链中的$^{32} $ si，$^{32} $ si，$^{32} $ si的活动。 Selena Neutrino实验将采用类似的策略，该实验将采用混合无定形的$^{82} $ SE/CMOS成像仪来执行$β-$ decay和太阳中微子的光谱。我们提出了Selena在100吨年的接触中实现零背景的拟议实验策略。
Highly pixelated solid-state detectors offer outstanding capabilities in the identification and suppression of backgrounds from natural radioactivity. We present the background-identification strategies developed for the DAMIC experiment, which employs silicon charge-coupled devices to search for dark matter. DAMIC has demonstrated the capability to disentangle and measure the activities of every $β$ emitter from the $^{32}$Si, $^{238}$U and $^{232}$Th decay chains in the silicon target. Similar strategies will be adopted by the Selena Neutrino Experiment, which will employ hybrid amorphous $^{82}$Se/CMOS imagers to perform spectroscopy of $ββ$ decay and solar neutrinos. We present the proposed experimental strategy for Selena to achieve zero-background in a 100-ton-year exposure.
