The angular and energy distributions of positive muons {mu}{sup +} and muonium M produced by the beam-foil method have been measured for the first time. A 7 MeV/c subsurface {mu}{sup +} beam was delivered to our apparatus from the Stopped Muon Channel at the Los Alamos Clinton P. Anderson Meson Physics Facility (LAMPF). The {mu}{sup +} formed M by electron capture in a thin Al target foil. A low pressure multi-wire proportional chamber upstream of the target foil was used both as a moderator and as a muon counter. To observe muonium, muons sere swept away by a bending magnet which was placed downstream of the target foil. This magnet was turned off while measuring the {mu}{sup +} distribution. Beyond the magnetic field, particles were collimated and then stopped by a microchannel plate detector located at various angles to the incident muon beam axis. Two pairs of scintillators mounted above (St) and below (Sb) the MC-P were used to detect the decay positrons to verify from the lifetime spectrum that the particles detected by the MCP are muons. The intensities of {mu}{sup +} and M emerging from the Al foil at different angles were obtained from both a time-of-flight spectrum and a lifetime spectrum.
