The ESS neutrino superbeam (ESSνSB) project is being studied as an upgrade to the European Spallation Source (ESS). This proposed upgrade consists of adding an H⁻ source to the existing beamline in order to send H⁻ pulses in between proton pulses, effectively doubling the beam power from 5 MW to 10 MW. In this contribution, we present the 2.5 GeV linear accelerator (linac) lattice and the...

The commissioning of the European Spallation Source (ESS) linac has started and that marks another important step towards the completion of the most powerful proton driver in the world with 5 MW of average beam power on target. Such impressive beam power could also be used for particle physics experiments at the intensity frontier. In particular, the ESS based super-beam project ESSnuSB plans...

The goal of the ESSνSB project is to discover and measure neutrino CP Violation with unprecedented sensitivity. The associated ESSνSB H2020 Design Study is aimed at investigating and proposing a conceptual design of a new neutrino superbeam in Europe. The Target Station is a key element of this project, since it will produce a high intensity neutrino superbeam from a 5 MW proton beam delivered...

The ENUBET project intends to reduce the flux related systematics in an accelerator neutrino beam to the 1% level by monitoring associated charged leptons produced in a narrow band meson beam. Large angle leptons from kaon decays are measured in an instrumented decay tunnel, while low angle muons from pions can be monitored after the hadron dump.

The European Spallation Source (ESS), currently under construction in Lund, Sweden, will be the brightest spallation neutron source in the world, when its driving proton linac. Such a high power requires production, efficient acceleration, and almost no-loss transport of a high current beam, thus making design and beam commissioning of this machine challenging. achieves the design power of 5...

237. Extinction Measurement at J-PARC MR with Slow-Extracted Pulsed Proton Beam for COMET ExperimentKyohei Noguchi (Kyushu University)08/09/2021, 13:40
The COMET experiment aims to search for the neutrinoless conversion of a muon to an electron in muonic atoms. This experiment utilizes a slow-extracted pulsed proton beam at 8 GeV from the J-PARC main ring synchrotron (MR). To achieve a sensitivity of $10^{-17}$, an extremely clean pulsed beam is required. In particular, an intensity ratio of leakage protons to the main pulsed beam, called...

ABSTRACT
The Fermi National Accelerator Laboratory (FNAL) Muon $g-2$ Experiment has measured the positive muon magnetic anomaly $a_{\mu} \equiv (g_{\mu}-2)/2$ with a precision of 0.46 parts per million, with data collected during its first physics run in 2018. The FNAL experimental result, combined with the measurement from the former experiment at Brookhaven National Laboratory, increases...

The existence of sterile neutrinos is an important question in our field. IsoDAR is a cyclotron-based electron antineutrino source that produces a pure, well-understood energy spectrum. IsoDAR generates high statistics, which when coupled with an inverse beta decay detector such as KamLAND, is capable of addressing observed anomalies attributed to sterile neutrinos at the 5 sigma level using...

Experimental muon source (EMuS) at China’s spallation neutron source (CSNS) is a multidisciplinary project intended mainly for μSR, muon induced x-ray emission (MIXE) and imaging applications, and secondary for muonium to antimuonium conversion physics or neutrino cross sections measurements. These goals are achieved by intense beams of surface and decay muons produced by pions decaying at...

A high-energy muon collider could be the most powerful and cost-effective collider approach in the multi-TeV regime, and a neutrino source based on decay of an intense muon beam would be ideal for measurement of neutrino oscillation parameters. Muon beams may be created through the decay of pions produced in the interaction of a proton beam with a target. The muons are subsequently accelerated...

Low emittance muon beams are central to the development of a Muon Collider and can significantly enhance the performance of a Neutrino Factory. The international Muon Ionization Cooling Experiment (MICE) has recorded several million individual muon tracks passing through a liquid hydrogen or a lithium hydride absorber and has demonstrated the ionization cooling of muon beams.

It is anticipated that high brightness muon beams will be needed primarily in two types of accelerators, a muon collider and a neutrino factory. The primary challenge posed by using muons for the working particle of an accelerator complex, and the reason they have not been used extensively, is the muon's short life-time (2.2μs at rest) and the relatively long cooling periods required by...

The Future Circular Collider is at the heart of the future vision of the European Strategy for Particle Physics, who placed, as the highest priority for Europe and its international partners, a technical and financial feasibility study of the 100km infrastructure and of the colliders that would be installed in it. The physics programme is based on the sequence of a 90-400 GeV high luminosity...
