Description
Accelerator Physics
Intense and high-energy proton beams are impacted onto fixed targets within the CERN’s accelerator complex to produce secondary particles (such as neutrons, antiprotons, kaons, pions, etc.) for physics experiments. A consolidation program of some of these particle-producing targets is currently ongoing at CERN. This includes the antiproton and neutron production targets (AD-Target and n_TOF...
The ESS neutrino superbeam project is being studied as an upgrade to the European Spallation Source. This would entail the addition of an H$-$ source to the existing beamline to send H$-$ pulses in between proton pulses, effectively doubling the beam power from five to ten megawatts. An obstacle to smooth operation is the intra-beam stripping of H$-$ within bunches, preliminary beam transport...
The 2.0 GeV, 5 MW proton linac for the European Spallation Source, ESS, will have the capacity to accelerate additional pulses and send them to a neutrino target, providing an excellent opportunity to produce an unprecedented high performance neutrino beam, the ESS neutrino Super Beam (ESSnuSB). ESSnuSB aims at measuring, with precision, the CP violating angle at the 2nd oscillation maximum...
The ESSnuSB project proposes the production of a European neutrino Super Beam for the discovery of the CP symmetry violation in the leptonic sector. For this purpose, an upgrade is under design of the 5 MW, 2 GeV proton beam from the LINAC of the European Spallation Source, currently under construction in Lund (Sweden), to obtain an additional 5 MW power beam dedicated to the neutrino...
Fermilab’s NuMI (Neutrinos at the Main Injector) provides an intense, high-energy flux of muon-neutrinos toward the far detector in Ash River, Minnesota for the NOvA experiment. It’s neutrino beamline target system is under upgrade with the goal to make the beamline components and associated support systems robust at beam power up to 1 MW. This talk will cover the NuMI beam operation status,...
EMuS (Experimental Muon Source) at CSNS (China Spallation Neutron Source) is a multidisciplinary project concerning very intense muon and pion beams mainly for muSR applications and particle physics. EMuS provides very intense beams by having as target system a unique superconducting capture solenoid incorporating a conical graphite target, with forward collection of muons and pions, and...
In nuSTORM facility pions are injected into the storage ring and a resulting circulating muon beam creates a neutrino flux with a perfectly know flavour content and spectrum. This makes nuSTORM an ideal laboratory to measure precisely neutrino interactions and to search for sterile neutrinos. Moreover, it may also offer to test novel concepts required for a future Muon Collider, like 6D...
The Muon Ionization Cooling Experiment (MICE) at RAL has collected extensive data to study the ionization cooling of muons. Several million individual particle tracks have been recorded passing through a series of focusing magnets in a number of different configurations and a liquid hydrogen or lithium hydride absorber. Measurement of the tracks upstream and downstream of the absorber has...
Multiple Coulomb scattering and energy loss are well known phenomena experienced by charged particles as they traverse a material. However, from recent measurements by the MuScat collaboration, it is known that the simulation code (GEANT4) available at the time overestimated the scattering of muons in low Z materials. Updates to GEANT4 have brought the simulations in line with the MuScat data...
The Muon Ionization Cooling Experiment, MICE, has demonstrated transverse emittance reduction through ionization cooling. Transverse ionization cooling can be used either to prepare a beam for acceleration in a neutrino factory or for the initial stages of beam cooling in a muon collider. Later stages of ionization cooling in the muon collider require the longitudinal emittance to be...
