Abstract:

The design and performance of a high-momentum, small phase-space volume muon beam is described. The muons are photoproduced by the bremsstrahlung of electrons incident on a thick target. Pion contamination is reduced to .000003 of muon flux by a 5.5 meter beryllium filter placed immediately after the target. The optical system has two stages of momentum analysis to give an almost dispersion free beam, and a final imaging stage to clean up the tails of the beam distribution. Standard B. N. L. 3Q48 and 18D72 magnets are used throughout. At 10 GeVc, the beam yields 100,000 muonssecond in a phase-space volume of .003 sq cm steradians and a momentum band of plus or minus 1.5. Author
