Overview of the ESSνSB Conceptual Design — •Tamer Tolba — Institut für Experimentalphysik, Universität Hamburg, Hamburg - Germany
In the search for the CP-violation in the leptonic sector, crucial information has been obtained from neutrino experiments. The measurement of the third neutrino mixing angle, θ13, opened the possibility of discovering the Dirac leptonic CP violating angle, δCP, with intense "super" neutrino beam experiments. In the light of these new findings, an urgent need has arisen to improve the detection sensitivity of the current long-baseline detectors, considering proton driver at MW scale with MegaTon scale detector, 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 to benefit from the high power of the ESS, LINAC in Lund-Sweden, to produce the world’s most intense second-generation neutrino beam, enabling measurement to be made at the second oscillation maximum. Assuming a ten-year exposure with five-years running in neutrino- and five-years in antineutrino-mode, CP-violation could be established with a significance of 5σ over more than 70% of all values of δCP. With the current design-study program of the experiment is coming to its successful end, with the production of the CDR, an overall status of the project will be presented. The technical aspects on the current design study programs running within the collaboration and the physics potential of the experiment will be presented, as well.
