A very low momentum, high purity positive muon beam has been developed at LAMPF, utilizing muons which originate from pion decays at rest in the target for the primary proton beam and are transported by the LAMPF stopped muon channel. The channel is tuned to transport muons with momenta as low as 3 MeV/c and hence selects muons originating some distance below the target surface (subsurface muons). A static E × B separator largely eliminates the e+ component in the beam.
