Description
The ESSnuSB design study is entering a new phase with a second four-year design study 2023-2026, ESSnuSBplus, funded by Horizon Europe. One of the ESSnuSBplus additions to ESSnuSB will be the design study of a low-energy nuSTORM (neutrinos from stored muons) facility based on the use of the ESS accelerator and the ESSNUSB accumulator-ring as injector complex. The nuSTORM facility consists of a dedicated target station with pion capture and transfer and a race-track storage ring in which the pions will be injected and, in the first race-track straight, decay to muons, which will be stored during many turns in the race-track ring. Each muon in the race-track ring will eventually decay producing a muon-neutrino and an electron-neutrino. In this way an intense neutrino beam containing both these species will be formed, which will be detected in a new, small near detector and in a far detector, the latter being the same as the near detector in the ESSnuSB project. nuSTORM will make possible precise measurements of both muon and electron neutrino cross sections in water as well as searches for sterile neutrinos. This talk will give and overview of the ESSnuSBplus project, with particular emphasis on the development of the nuSTORM facility.
