论文摘要
Katrin（Karlsruhe Tritium Neutrino）实验研究了Tritium beta-decay Spectrum的能量终点，以确定电子抗神经的有效质量。该合作报告了这次TAUP-2019会议上的第一个质量测量结果。 Tristan项目旨在通过使用升级的Katrin系统测量整个Tritium beta-decay Spectrum来检测KEV-STERILE中微子签名。最大的挑战之一是处理Katrin Tritium源的强大活性产生的高信号速率，同时保持良好的能量分辨率。因此，一种新型的多像素硅漂移检测器和读出系统的设计旨在处理约100 mcps的速率，其能量分辨率优于300 eV（FWHM）。该报告简洁地提出了Katrin实验，即Tristan项目，然后是第一个7像素原型测量运动的结果，最终描述了由166个SDD像素组成的第一个Tristan模块以及在Katrin实验中的实现。
The KATRIN (Karlsruhe Tritium Neutrino) experiment investigates the energetic endpoint of the tritium beta-decay spectrum to determine the effective mass of the electron anti-neutrino. The collaboration has reported a first mass measurement result at this TAUP-2019 conference. The TRISTAN project aims at detecting a keV-sterile neutrino signature by measuring the entire tritium beta-decay spectrum with an upgraded KATRIN system. One of the greatest challenges is to handle the high signal rates generated by the strong activity of the KATRIN tritium source while maintaining a good energy resolution. Therefore, a novel multi-pixel silicon drift detector and read-out system are being designed to handle rates of about 100 Mcps with an energy resolution better than 300 eV (FWHM). This report presents succinctly the KATRIN experiment, the TRISTAN project, then the results of the first 7-pixels prototype measurement campaign and finally describes the construction of the first TRISTAN module composed of 166 SDD-pixels as well as its implementation in KATRIN experiment.
