Optimization of a neutrino beam for the study of CP violation with the LENA detector — Christoph Genster, •Marta Meloni, Michael Soiron, Achim Stahl, Marcel Weifels, and Christopher Wiebusch — RWTH Aachen University - III. Physikalisches Institut B
Neutrino beams are nowadays a commonly used and well investigated tool to study neutrino oscillations, e.g. T2K, NOνA experiments. Beam neutrinos are produced by the decays of properly focused particles, mostly pions and kaons, generated by the collisions of accelerated protons with a target. The shape and composition of the obtained neutrino fluxes depend on the properties of the neutrino production apparatus. Primary beam, target, focusing system, decay tunnel must be optimized relatively to the neutrino detector, in order to achieve the highest possible sensitivity to oscillation parameters such as the CP-violating phase δcp. This talk will focus on the optimization of a neutrino beam from the European Spallation Source (ESS) in Lund, Sweden, to the liquid scintillator neutrino detector LENA, proposed in the Pyhäsalmi mine in Finland.
