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 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.
A general overwiev of the ENUBET physics...
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...
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...
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.
Previous...
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...
