Producing an Intense, Cool Muon Beam via e+e− Annihilation∗
نویسندگان
چکیده
We consider a highly unconventional approach to generating muon and antimuon bunches for a neutrino factory or muon collider: electronpositron annihilation just above muon-antimuon threshold. This approach can produce low-emittance bunches at high energy, easing the muoncooling and acceleration challenges in such facilities. However, the small (< 1μb) useable production cross section means that extraordinary beampower and targeting challenges would have to be met. We speculate on what this might entail.

An Intense Low Energy Muon Source for the Muon Collider
A scheme for obtaining an intense source of low energy muons is described. It is based on the production of pions in a high field magnetic bottle trap. By ensuring efficient slowing down and extraction of the decay muons an intense intermediate energy muon beam is obtained. For the specific case of negative muons a novel technique called frictional accumulation provides efficient conversion int...
متن کاملMuon Cooling, Muon Colliders, and the MICE Experiment
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...
متن کاملMuon Ionisation Cooling Experiment MICE
The Muon Ionisation Cooling Experiment (MICE) is currently under construction at the Rutherford Appleton Laboratory. MICE will prove the technology necessary for muon ionisation cooling. In ionisation cooling, particle beam emittance is reduced by passage through an energy absorbing medium and RF cavities. In its final configuration, MICE will consist of a 5.5 metre cell of an ionisation coolin...
متن کاملDesign for a Muon Front End with Magnetically Shielded RF Cavities
In the baseline Neutrino Factory muon front end, strong, closely spaced solenoid magnets are used to contain the high emittance muon beam. In addition, significant acceleration is required for bunching, phase rotation and cooling, requiring RF cavities operating near to their maximum achievable gradient. There are experimental indications that RF cavities may not be able to achieve these large ...
متن کاملMuon Transverse Ionization Cooling: Stochastic Approach Typeset Using Revt E X 1
The muon transverse ionization cooling is modeled as a Brownian motion of the muon beam as it traverses a Li or Be rod. A Langevin like equation is written for the free particle case (no external transverse magnetic eld) and for the most realistic harmonically bound beam in the presence of a focusing magnetic eld.
