Description
At the Karlsruhe Institute of Technology (KIT), a full-scale replica of the KATRIN experiment’s detector system was developed to pretest the innovative TRISTAN detector modules. This replica enables comprehensive testing and calibration of up to nine TRISTAN detector modules under controlled conditions, ensuring optimal performance before their integration into the KATRIN beamline in 2026. This upgrade aims to enhance KATRIN’s sensitivity in the search for keV-scale sterile neutrinos. Preliminary results demonstrate that the TRISTAN modules deliver exceptional high-resolution for beta spectroscopy, which is essential for precise neutrino mass measurements and the exploration of potential new physics.
During operation in the KATRIN beamline, the detector modules will be exposed to a strong magnetic field. To investigate its influence on critical detector parameters, dedicated measurements were performed using the TRISTAN replica setup. In addition, long-term stability studies of the detector performance were conducted over extended data-taking periods.
The poster will show these results and highlight the excellent properties of the TRISTAN detector modules, the stable detector response and calibration behavior.
