Status of the ESSνSB Target Station

The goal of the ESS𝜈SB project is to discover and measure neutrino CP violation with unprecedented sensitivity. The associated ESS𝜈SB H2020 Design Study is aimed at investigating and proposing a conceptual design of a new neutrino superbeam in Europe. The Target Station is a key element of this project, since it will produce a high intensity neutrino superbeam from a 5MW proton beam delivered by the European Spallation Source at Lund. Work Package 4 of this project focuses on the optimization of the physics performance of the elements producing the beam, such as the targets and the magnetic horns, as well as on the technical aspects related to the Target Station design. The 5MW proton beam will be split laterally into four 1.25MW beams, each with 1.3 μs proton pulses and 14 Hz repetition rate, which will hit four separate targets inserted inside four horns. The production of the neutrino beam under such conditions requires the development of technologies capable of working at a MW power scale, both for the target and for the other components of the target station facility.
