ESSnuSB is a Design Study for an experiment which will measure CP violation in the lepton sector by observing neutrino oscillations at the second muon neutrino to electron neutrino oscillation maximum. The signal of CP violation at the second oscillation maximum is expected to be close three times larger than at the first one, which significantly increases the ratio between the signal and the systematic uncertainty, and thereby the physical reach of the project. The very intense muon neutrino beam will be generated by uniquely powerful ESS linear proton accelerator, which is currently under construction near Lund, Sweden. The oscillation signature will be measured by observing neutrino interactions in the large 538 kt fiducial volume of the far water Cherenkov detectors. The experiment will also feature near detectors which will be used to measure neutrino interaction cross-sections and the non-oscillated flux. This seminar will start with a short introduction to CP violation in neutrino oscillations, focusing on the oscillation channels relevant for ESSnuSB. It will continue with the description of the design of the ESSnuSB experimental setup, and conclude with the expected physics reach of the project.
