Development of new target stations and water-Cherenkov detectors

Progress on the overall project status

Abstract

The ESSnuSB is a design study for a long-baseline neutrino experiment to precisely measure the CP violation in the leptonic sector, at the second neutrino oscillation maximum, using a beam driven by the uniquely powerful ESS linear accelerator. The ESSnuSB-plus (ESSnuSB+) design study program, which is an extension phase of the ESSnuSB project, aims in designing two new facilities, a Low Energy nuSTORM and a Low Energy Monitored Neutrino Beam and use them to precisely measure the (anti)neutrino-nucleus cross-section in the energy range of 200-600 MeV, where experimental data are lacking or imprecise. In addition, new target stations and a new water-Cherenkov near-near detector will be designed to measure cross sections and serve to explore sterile neutrino physics. An overall status of the project will be presented together with the ESSnuSB+ additions.
