– The ESSnuSB Conceptual Design Report is now published by

The European Physical Journal Special Topics

– The new proposal, ESSnuSB+, submitted to the EU last April, has been approved this July.

Objectives and Ambitions of the new project:

The key objective of the H2020 ESSνSB Design Study was to demonstrate the feasibility of using the European Spallation Source proton linac to produce the world’s most intense neutrino beam concurrently with the 5 MW proton beam that will be used for the production of spallation neutrons. After the production of all deliverables and the publication of the ESSνSB CDR, this is now accomplished. The present Design Study is proposed to pave the way of ESSνSB by introducing complementary studies and enlarging its scope by introducing investigations of synergetic projects. The ESSνSB+ strategic objectives are:
1)  Make all necessary civil engineering and geotechnical studies needed for the facility implementation of the ESSνSB/ ESSνSB+ technical facilities at the ESS site and at the far detector side.
2)  Study the implementation of a special target station for pion production and extraction for injection to a Low Energy nuSTORM decay ring and Low Energy Monitored Neutrino Beam decay tunnel.
3)  Study the Low Energy nuSTORM decay ring and the injection of pions and muons coming from the special target station.
4)  Study the Low Energy Monitored Neutrino Beam instrumented decay tunnel and the injection of pions coming from the special target station.
5)  Study the design of a common detector for the Low Energy nuSTORM and for the Low Energy Monitored Neutrino Beam sub-projects for measurement of the neutrino cross-sections of interest.
6)  Investigate the possibility of the utilisation of the Low Energy nuSTORM with its near detector and the ESSνSB near detector, already designed, for sterile neutrino searches.
7)  Carry out studies of the geotechnical characteristics of the currently preferred site at Zinkgruvan for the underground ESSνSB far detector and study its potential for astroparticle physics programme.
8)  Promote the ESSνSB/ESSνSB+ projects to their stakeholders, including scientists, politicians, funders, industrialists and the general public in order to have it included in the ESFRI list, which will allow to carry out extensive R&D work leading to a Technical Design Report for the whole facility.
