The formation of an antihydrogen beam by transporting an antiproton beam through an electron-positron plasma that produces magnetobound positronium is studied using a classical trajectory simulation. Through simulation, it is found that antihydrogen can be synthesized via three body recombination involving magnetobound positronium. It has previously been reported that giant cross-magnetic-field particle drifts can occur as a result of binary collisions between charged matter particles and their antimatter counterparts. An electron-positron pair collision can result in a correlated drift of the two particles, perpendicular to a magnetic field. While the two particles remain in their correlated drift, they are referred to as magnetobound positronium. This study was conducted to determine what would happen if a magnetobound positronium system encountered an antiproton. The simulation shows that a positron can be captured into a bound state with an antiproton. This study also considers the effect that the electron-positron collision pitch angle has on antihydrogen production via magnetobound positronium.
