论文摘要
R2D2 R＆D项目研究了可能使用球形比例计数器来搜索中微子双β衰减。双重电荷和闪烁光读数可能会改善检测器性能。使用6x6 mm2硅光电倍增体用1.1 bar的纯氩测试。首次使用闪烁光在球形比例计数器中触发。测得的漂移时间与模拟的期望非常吻合。此外，在雪崩开发过程中发出的光信号展示了可以利用的事件表征的特征。
The possible use of a Spherical Proportional Counter for the search of neutrinoless double beta decay is investigated in the R2D2 R&D project. Dual charge and scintillation light readout may improve the detector performance. Tests were carried out with pure argon at 1.1 bar using a 6x6 mm2 silicon photomultiplier. Scintillation light was used for the first time to trigger in a spherical proportional counter. The measured drift time is in excellent agreement with the expectations from simulations. Furthermore the light signal emitted during the avalanche development exhibits features that could be exploited for event characterisation.
