Thermal muonium (positive muon {mu}{sup +} and electron {ital e}{sup {minus}}) atoms were produced from the surface of a hot (2300 K) and high purity tungsten foil placed at the primary beam of 500 MeV pulsed protons. Resonant ionization (1{ital s}{r_arrow}2{ital p}{r_arrow}unbound) of the thermal muonium with pulsed laser sources was achieved with reference to thermal hydrogen isotopes (D and T) so as to produce a potentially intense ultraslow (as low as 0.2 eV) positive muon beam with an extremely narrow phase-space volume and high stopping density.
