A process for producing antihydrogen includes providing low energy antiprotons and positronium atoms within an interaction volume. Thermalized positrons are derived by moderating high energy positrons obtained from a high energy source, such as 22Na. The thermalized positrons are directed by electrostatic lenses to a positronium converter, positioned adjacent a low energy (less than about 50 KeV) circulating antiproton beam confined within an ion trap. Collisions between antiprotons and ortho-positronium atoms generate antihydrogen, a stable antimatter species, with substantial probability.
