Study of the use of the ESS facility to accurately measure the neutrino cross-sections for ESSnuSB leptonic CP violation measurements and to perform sterile neutrino searches and astroparticle physics

Descrizione del progetto

Trarre il meglio dalla prossima grande struttura scientifica

Dopo il Big Bang, materia e antimateria sono state prodotte in proporzioni identiche attraverso la materializzazione delle enormi quantità di energia rilasciate. Oggi, tuttavia, non esiste antimateria nell’universo. Per studiare questo problema fondamentale, il progetto ESSnuSB, finanziato dall’UE, si è dedicato a dimostrare la fattibilità dell’utilizzo del potente acceleratore di protoni, unico al mondo, della Fonte di spallazione europea (ESS, European Spallation Source), attualmente in costruzione a Lund. Il progetto ESSnuSBplus, finanziato dall’UE, esaminerà ora i requisiti di ingegneria civile per le costruzioni sotterranee dell’infrastruttura di ricerca proposta da ESSnuSB e studierà la realizzazione di una seconda speciale stazione bersaglio, di un anello per muoni a bassa energia di nuSTORM e di un tunnel dotato di strumentazioni per il fascio di neutrini a bassa energia monitorato, da utilizzare per le misurazioni esatte della sezione d’urto dei neutrini necessarie per il progetto ESSnuSB.

Obiettivo

After the success of the H2020 ESSνSB Design Study proving the feasibility of the upgrade of the European Spallation Source to become, in addition to a neutron facility, also a very competitive neutrino facility, we propose here a study to reinforce and develop complementary features to this proposal in order to improve and widen the scientific and technological scope.
The key objective of the H2020 ESSνSB Design Study was to demonstrate the feasibility of using the European Spallation Source (ESS) proton linac to produce the world's most intense neutrino beam concurrently with the 5 MW proton beam to be used for the production of spallation neutrons. After accomplishing all deliverables and the publication of the ESSνSB CDR, this is now fully demonstrated. With the present Design Study, it is proposed to take further steps towards its realization by introducing complementary studies and enlarging its scope by making studies on synergetic aspects of the project.
The ESSνSB+ high-level objectives are to:
• Study the civil engineering needed for the facility implementation at the ESS site as well as those needed for the ESSνSB far detector site.
• Study the feasibility and implementation of a special target station for pion production and extraction for injection to a low energy nuSTORM decay ring and to a low energy Monitored Neutrino Beam decay tunnel, for neutrino cross-section measurements.
• Study the low energy nuSTORM decay ring and the injection of the pions and muons from the special target station.
• Study the low energy ENUBET-like Monitored Neutrino Beam decay tunnel and the injection of the pions and muons from the special target station.
• Study the capabilities of the proposed setup for sterile neutrino searches and astroparticle physics.
• Promote the ESSνSB project proposal to its stakeholders, including scientists, politicians, funders, industrialists and the general public in order to pave the way to include this facility in the ESFRI list.
