摘要:

惰性中微子是粒子物理学标准模型的最小扩展。一个有希望的独立于模型的方法来寻找无菌中微子是通过高精度β光谱。卡尔斯鲁厄氚中微子(KATRIN)实验配备了一个新的多像素硅漂移探测器焦平面阵列和读出系统,称为TRISTAN探测器,有可能取代以前的实验室为基础的搜索灵敏度。在这项工作中,我们提出的第一个硅漂移探测器原型与电子的特性,我们调查的不确定性的影响,最终无菌中微子灵敏度的检测器的电子响应。

英文摘要:

Sterile neutrinos are a minimal extension of the Standard Model of Particle Physics. A promising model-independent way to search for sterile neutrinos is via high-precision beta spectroscopy. The Karlsruhe Tritium Neutrino (KATRIN) experiment, equipped with a novel multi-pixel silicon drift detector focal plane array and read-out system, named the TRISTAN detector, has the potential to supersede the sensitivity of previous laboratory-based searches. In this work we present the characterization of the first silicon drift detector prototypes with electrons and we investigate the impact of uncertainties of the detector's response to electrons on the final sterile neutrino sensitivity.
