Reduction of stored-particle background by a magnetic pulse method at the KATRIN experiment.

The KATRIN experiment aims to determine the effective electron neutrino mass with a sensitivity of 0.2\,{\text{eV}/c^2}(90\% C.L.) by precision measurement of the shape of the tritium \textbeta-spectrum in the endpoint region. The energy analysis of the decay electrons is achieved by a MAC-E filter spectrometer. A common background source in this setup is the decay of short-lived isotopes, such as \textsuperscript{219}n and...
