Status of the ESSνSB Target Station — •Tamer Tolba — Institut für Experimentalphysik, Universität Hamburg, Hamburg - Germany

In the quest to discover CP-violation in the leptonic sector, a crucial information has been obtained from reactor experiments demonstrating that the value of the third neutrino-mixing angle, θ₁₃, is higher than its previously defined standard value. In the light of this new finding, an urgent need has arisen to improve the detection sensitivity of the current long-baseline detectors, with a key modification to place the far detectors at the second, rather than the first, oscillation maximum.

The European Spallation Source Neutrino Super Beam (ESSνSB) aims at searching for CP-violation in the leptonic sector, at 5σ significance level in more than 60% of the leptonic Dirac CP violating phase range, and measuring the CP phase angle with high precision by setting the neutrino source-to-detector distance, the baseline, at the second oscillation maximum. Several technological challenges must be precisely studied and simulated before addressing the design of the ESSνSB detector. Among these, the finite element and physics simulations of the target station and the neutrino beam are considered to be highest priority at this phase of the ESSνSB project.

Here I will shed light on the current target station design physics and FEA simulation efforts of the ESSνSB WP4 working group.
