“…In its current design, the accumulator ring has a circumference of 384 m. It will consists of a lattice divided in four arcs and four straight sections [10]. The H − ion beam, divided in 4 batches with a separation gap of 0.1 ms, will be injected in the accumulator ring through multiturn injection.…”

The ESS 5 MW linac will be the world's most powerful accelerator, enabling with its 10 16 2 GeV protons per second the production of the world's most intense flux, not only of neutrons, but also of neutrinos and muons. This opens unique opportunities for High Intensity Frontier fundamental physics. The EU supported Design Study of an ESS neutrino Super Beam (ESSνSB) for long baseline neutrino oscillation measurements, based on an upgrade of the ESS facility, has been under way since 2018 with the participation of physicists from fifteen European institutions. In this study is designed the upgrade of the facility in order to increase the linac power to 10 MW by the provision of extra H − pulses between the proton linac pulses and provide a ca 400 m circumference accumulator ring to compress the 3 ms long linac pulses to 1.3 µs, a set of four highpower neutrino targets with focusing horns and a kiloton near and a megaton far water Cherenkov neutrino detector, the latter at a location of 360 km, alternatively 540 km, from ESS, both of which are near the location of the second neutrino oscillation maximum. The time of the publication of the ESSnuSB Design Study report is approaching and highlights among achieved design results are presented. Recently a study of the use of the intense muon flux produced concurrently with neutrinos has been started, aiming at a design of, in the first stage, a nuSTORM low-energy facility and a Proton Complex for production of 2 ns 10 15 proton bunches for a future Muon Collider. The plan for this High Intensity Frontier Initiative (HIFI) design work is presented.

“…For instance, a dedicated study of a ∼300 kA horn with a 12.5 Hz repetition rate had been carried out for the European Neutrino Superbeam (EUROνSB) [114,116,117]. More recently, the European Spallation Source Neutrino Superbeam (ESSνSB) [31,118], which would operate a proton extraction of 2.68 ms pulses of ∼10 15 protons repeated at 14 Hz, has chosen to develop a dedicated accumulator ring to compress the proton pulses to some µs of temporal length [32,119], in order to exploit standard horn technologies. The burst-mode slow extraction developed at the SPS as an option for the ENUBET monitored beam (Section 3, Figure 3) also requires dedicated horn studies.…”

Neutrino oscillation physics has entered a new precision era, which poses major challenges to the level of control and diagnostics of the neutrino beams. In this paper, we review the design of high-precision beams, their current limitations, and the latest techniques envisaged to overcome such limits. We put emphasis on “monitored neutrino beams” and advanced diagnostics to determine the flux and flavor of the neutrinos produced at the source at the per-cent level. We also discuss ab-initio measurements of the neutrino energy–i.e., measurements performed without relying on the event reconstruction at the ν detector–to remove any flux induced bias in the determination of the cross sections.
