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 into a 1 0 keV ~tbeam whose emittance is then reduced in a configuration providing extended frictional cooling. The result is a beam of very small transverse and longitudinal emittance that can be used together with an equivalent IX + beam as a compact intense muon source for the Ix+~t collider. A final luminosity around 1034 crn -2 s 1 is expected to be obtained at 2 TeV.
