Poster Neutrino mass Poster


This poster shows the use of Zonal Harmonic Field Expansion for fast electric and magnetic field simulations with the superposition principle, and for near-realtime adiabatic electron tracking. Various measurements in the KATRIN experiment require special main spectrometer coil current and electrode potential configurations, most prominently the recent Shifted Analyzing Plane background reduction method (arXiv:2201.11743). The high-performant simulations presented here enable interactive design and improvement of these configurations by simulation of their spectrometer properties.
