Description
The ESSnuSB+ project aims to produce an intense neutrino beam using the high-power proton linac of the European Spallation Source (ESS). A key element of the facility is the target station, where a 2.5 GeV proton beam interacts with a granular titanium-sphere target to generate an intense pion-meson beam. These pions are focused by a magnetic horn and directed toward a storage ring before decaying into the muons that will be stored in the ring while emitting the neutrinos.
In this work, detailed FLUKA simulations are used to model the full chain of particle production and energy deposition across major components of the target station. The simulations quantify the spatial distribution of deposited power and radiation dose. These results are essential for validating the feasibility of the target design, assessing component lifetime, and informing the engineering of cooling and shielding systems.
Furthermore, updated predictions of the pion production are presented, representing the first step in the optimisation of the neutrino production for the ESSnuSB+ experiment. These results contribute to the overall design validation of the facility.
