Abstract

The European Spallation Source linear proton accelerator will have a uniquely high power of 5 MW. The modifications and additions to the accelerator that are required to enable the generation of a uniquely intense neutrino Super Beam ESS{\nu}SB for measurement of leptonic CP violation using a large water Cherenkov detector are described. ESSnuSB is complementary to the other two proposed Super Beam experiments Hyper-K and DUNE by the fact that the resulting high neutrino beam intensity allows to place the neutrino detector at the second oscillation maximum. The simulated performance of the ESS{\nu}SB experiment is compared to the other two experiments under the assumption of the same systematic errors in all three experiments. The performance of ESS{\nu}SB for CP violation precision measurements is found to be highly competitive.
