Description
The measurement of the third neutrino mixing angle, 𝜃13, in 2012, opened the possibility of discovering the Dirac leptonic CP violating angle, 𝛿𝐶𝑃 , with intense "super" neutrino beam experiments. In light of these new findings, an urgent need has arisen to improve the detection sensitivity of the current long-baseline detectors, considering proton drivers on the MW scale with MegaTon scale detectors, as key feature the location of the far detectors at the second, rather than the first, oscillation maximum.
The European Spallation Source neutrino Super Beam (ESS𝜈SB) will use the high power of the ESS LINAC in Lund-Sweden, to produce the world’s most intense neutrino beam, enabling measurement to be made at the second oscillation maximum. Assuming a ten-year exposure, with five years running in neutrino-mode and five years in antineutrino-mode, the ESS𝜈SB will have the capacity to establish CP-violation with a significance of 5𝜎 over more than 70% of all values of 𝛿𝐶𝑃 . The current design-study program of the experiment is currently coming to its successful end with the production of the CDR. An overall technical status of the project and its physics potential will be presented.
