The ESSnuSB (European Spallation Source neutrino SuperBeam) design study has been completed. This long baseline neutrino experiment aims to measure the charge-parity (CP) violating phase in the leptonic sector.

To further improve the experiment's precision, an understanding of the neutrino interaction cross-section is critical. This can be achieved using a facility known as the nuSTORM (Neutrinos from STORed Muon beam) facility. The primary component of the facility is a racetrack-shaped magnetic beamline designed to collect and store muons for controlled neutrino production. The precisely controlled neutrino flux makes it possible to measure absolute cross-section with high precision, and explore the potential existence of sterile neutrinos.

This seminar will describe the progress on the muon storage ring and an estimate of the neutrino flux.
