The ESSnuSB project aims to measure the leptonic CP violation at the second neutrino oscillation maximum using an intense neutrino beam, which will be produced by the powerful ESS proton linear accelerator. The first phase of the project was successfully concluded with the production of the Conceptual Design Report in which it was shown that this next-to-next generation neutrino oscillation experiment has a potential to start the precision era in the field of the leptonic CP violation measurement.

ESSnuSB+ is a continuation of this study which focuses on neutrino interaction cross-section measurement at the low enutrino energy region, exploring the sensitivity of the experimental set-up to additional physics scenarios and on the civil engineering of the near and far detectors sites. It foresees an intermediate step in the ESSnuSB construction phase in which a number of additional facilities will be built: a 1/4 power ESSnuSB neutrino production target system prototype, a low energy muon storage ring and a low energy monitored neutrino beam facility; a common near neutrino detector for the muon ring and monitored beam will be designed, and a study of the effect of Gd doping of ESSnuSB water Cherenkov detectors will be performed.
