Description
The TRISTAN (TRitium Investigation on STerile to Active Neutrino mixing) detector aims at searching for keV-sterile neutrinos in the full beta decay spectrum of tritium using a novel detector system at the KATRIN experiment.
This detector will consist of more than 1000 Silicon Drift Detector (SDD) pixels, arranged in so-called detector modules. The SDD modules are now in production and the commissioning of the first phase of the project is expected to begin in 2025. Thanks to the high tritium source activity of KATRIN a statistical sensitivity at the level of sin2θ<10-6 can be reached. The challenge, however, is the precise modelling of the spectrum at the ppm-level.
In this poster we will present the on-going efforts to model the expected tritium spectrum at the detector. The dominant systematic uncertainties as well as the expected sensitivity of the KATRIN experiment will be reported.
