Abstract

Sterile neutrinos in the keV mass range present a viable candidate for dark matter. They can be detected through single β -decay, where they cause small spectral distortions. The Karlsruhe Tritium Neutrino (KATRIN) experiment aims to search for keV-scale sterile neutrinos with high sensitivity. To achieve this, the KATRIN beamline will be equipped with a novel multi-pixel silicon drift detector focal plane array named TRISTAN. In this study, we present the performance of a TRISTAN detector module, a component of the eventual 9-module system. Our investigation encompasses spectroscopic aspects such as noise performance, energy resolution, linearity, and stability.

开发硅漂移探测器阵列，利用 KATRIN 实验搜索 keV 级不育中微子

质量范围在 keV 的无育中微子是暗物质的可行候选者。它们可以通过单次β衰变被探测到，在这种情况下，它们会造成较小的光谱畸变。卡尔斯鲁厄氚中微子（KATRIN）实验旨在以高灵敏度搜索 keV 质量级的不育中微子。为此，KATRIN 光束线将配备一个名为 TRISTAN 的新型多像素硅漂移探测器焦平面阵列。在本研究中，我们介绍了 TRISTAN 探测器模块的性能，该模块是最终 9 模块系统的组成部分。我们的研究包括光谱学方面，如噪声性能、能量分辨率、线性度和稳定性。
