Abstract The KArlsruhe TRItium Neutrino (KATRIN) Experiment aims for the determination of the effective mass of the electron-antineutrino. KATRIN uses a strong, gaseous, windowless tritium source for precision spectroscopy of the β-electrons. The 70-m-long experiment has been set up at the Tritium Laboratory Karlsruhe (TLK) and was commissioned with traces of tritium during two measurement campaigns in 2018. In spring 2019, the first campaign with full source luminosity started. KATRIN uses a complex gas-handling system called Loops for stabilized injection of tritium into the source and tritium gas handling. It also makes use of the unique facilities and possibilities found at the TLK for gas handling, cleanup, and purification. This paper describes the integration of KATRIN into TLK’s existing infrastructure and the current status of the experiment and concludes with a summary of the tritium measurements.

氚处理系统和 KATRIN 实验的第一次氚操作

摘要 卡尔斯鲁厄氚中微子 (KATRIN) 实验旨在确定电子反中微子的有效质量。KATRIN 使用强、气态、无窗氚源进行 β 电子的精密光谱分析。该 70 米长的实验已在卡尔斯鲁厄氚实验室 (TLK) 进行，并在 2018 年的两次测量活动中进行了氚痕量测试。 2019 年春季，第一个具有全光源亮度的活动开始了。KATRIN 使用称为 Loops 的复杂气体处理系统来稳定氚注入源和氚气体处理。它还利用 TLK 的独特设施和可能性进行气体处理、净化和净化。
