چکیده
We analyze the design of a high energy 11 +Wcollider based on electro-production of muons. We derive an expression for the luminosity in terms of analytic formulae for the electron-to-muon conversion efficiency and the electron beam power on the production target . On the basis of studies of self-consistent sets of collider parameters under "realistic" ("optimistic") assumptions about available technology with beam cooling, we find the luminosity limited to 10 27 cm -2 s-1 (1028 cm -2 s-1 ) . We also identify major technological innovations that will be required before W+ wcolliders can offer sufficient luminosity (103° cm-2 s-1 ) for high energy physics research .

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 کاملParticle Production and Survival in Muon Acceleration
Because of the relative immunity of muons to synchrotron radiation, the idea of using them instead of electrons as probes in high-energy physics experiments has existed for some time, but applications were limited by the short muon lifetime. The production and survival of an adequate supply of low-emittance muons will determine the available luminosity in a high-energy physics collider. In this...
متن کاملAtmospheric muons and neutrinos from charm
We have updated our previous investigation of the production of muons and neutrinos in cosmic ray interactions with the atmosphere, taking account of recent results from the ep collider HERA in our QCD-based model for hadronic interactions. Qualitatively, our previous results remain unmodi ed: our predictions for the conventional muon and neutrino uxes agree with earlier calculations, whereas t...
متن کاملBunch Coalescing in a Helical Channel
A high-luminosity Muon Collider requires bunch recombination for optimal luminosity. In this paper, we take advantage of the large slip factor attainable in a helical transport channel (HTC) to coalesce bunches of muons into a single one over a shorter distance than can be achieved over a straight channel. INTRODUCTION A muon collider provides a possible path for the U.S. to return to the high ...
متن کاملThe Bethe-Heitler Process as a Source of Muons
in high-energy photon interactions with a nucleus A, as recently suggested in [7] (slide 23). Of course, muon-pair production by this process is suppressed relative to electron-positron pair production by the ratio (me/mμ) 2 ≈ 1/40, 000, so there is an issue of the efficiency of muon production via reaction (1). The Bethe-Heitler process (1) is further suppressed near threshold, so it would be ...
