The ESS 5 Megawatt linac will be the world’s most powerful accelerator, enabling with its 1016 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. An EU supported Design Study of an ESS neutrino Super Beam (ESSnuSB) is under way since 2018 with the participation of physicists from 15 European institutions of the use of the neutrino beam for long baseline neutrino oscillations. Within this study is being designed the upgrade of the linac required to increase its power to 10 MW by the provision of extra H- pulses between the proton linac pulses, of a ca 400 circumference accumulator ring to compress the 3ms long linac pulses to 1.3µs, of a set of four high power neutrino targets with focusing horns and a kiloton near and a megaton far water Cherenkov neutrino detector, the latter at a distance of 540 km at the location of the second neutrino oscillation maximum. The publication of the ESSnuSB Design Study report is approaching and highlights among achieved design results will be presented. More recently a study of the use of the intense muon flux produced together with neutrinos has been started, aiming at a design of, in the first stage, a Muon Cooling Test Facility to be followed by the study of a nuSTORM low-energy facilty, a Neutrino Factory and ultimately a Muon Collider Higgs Factory. The plan for this High Intensity Frontier Initiative (HIFI) design work will be presented.
