Muon ionization cooling is the only solution to prepare high brilliance muon beams necessary for a Neutrino Factory or Muon Collider. The International Muon Ionization Cooling Experiment (MICE) is under development at the Rutherford Appleton Laboratory (RAL). A dedicated beam line generates a range of input emittances and momenta, with time-of-flight (TOF) and Cherenkov detectors to ensure a pu...
The international Muon Ionization Cooling Experiment (MICE) will perform a systematic investigation of ionization cooling with muon beams of momentum between 140 and 240 MeV/c at the Rutherford Appleton Laboratory ISIS facility. The measurement of ionization cooling in MICE relies on the selection of a pure sample of muons that traverse the experiment. To make this selection, the MICE Muon Beam...
Muon colliders and neutrino factories are attractive options for future facilities aimed at achieving the highest lepton-antilepton collision energies and precision measurements of parameters of the Higgs boson and the neutrino mixing matrix. The performance and cost of these depend on how well a beam of muons can be cooled. Recent progress in muon cooling design studies and prototype tests nou...
Muon acceleration is one of the more difficult stages to develop for a Neutrino Factory or Muon Collider. The large transverse and longitudinal admittances which must be designed into the system and the rapidity with which acceleration must take place because of muon decay preclude the use of conventional synchrotron design. The approach here employs fixed-field architectures for muon accelerat...
This article reviews the current theoretical and experimental status of the field of muon decay and its potential to search for new physics beyond the Standard Model. The importance of rare muon processes with lepton flavor violation is highly stressed, together with precision measurements of normal muon decay. Recent up-to-date motivations of lepton flavor violation based on supersymmetric mod...
Large energy spread of muon beams can be reduced by so-called phase rotation. It requires rather low frequency or long slope in the RF waveform and rather high gradient field against the short muon lifetime. Because such a low frequency high gradient RF cavity is difficult to construct, a high frequency bunching system is proposed. The bunching system located after 100m from a production target...
The anomalous magnetic moment of the negative muon has been measured to a precision of 0.7 ppm (ppm) at the Brookhaven Alternating Gradient Synchrotron. This result is based on data collected in 2001, and is over an order of magnitude more precise than the previous measurement for the negative muon. The result a(mu(-))=11 659 214(8)(3) x 10(-10) (0.7 ppm), where the first uncertainty is statist...
Selected experiments in muon physics would add a strong component to the scientific program at a neutrio factory. The muon fluxes that could be available at such a facility would permit a search for a permanent electric dipole moment of the muon at the ≤ 10 −25 e-cm level, thus presenting the unique opportunity to search for an EDM in a second-generation particle. The muon to electron coherent ...
Backgrounds from punchthrough particles originating from minimum bias events and inclusive QCD jets in the CMS barrel muon system has been simulated using a detailed GEANT description of the Technical Design Report geometry and shielding. Rates due to punchthrough in the entrance at each muon station as well as rates of hits, produced by these punchthrough particles, are given as a function of ...
We present an accurate model of the muon-induced background in the DAMA/LIBRA experiment. Our work challenges proposed mechanisms which seek to explain the observed DAMA signal modulation with muon-induced backgrounds. Muon generation and transport are performed using the MUSIC/MUSUN code, and subsequent interactions in the vicinity of the DAMA detector cavern are simulated with Geant4. We esti...
