"The collaboration reports success in producing antihydrogen in a so-called Cusp trap, an essential precursor to making a beam."

The article doesn't really say, but why are beams needed? Is it because these (anti-)particles are always moving or have such a short lifespan, or is there some other reason beams are so important?

(The sci-fi nerd in me first thought of weaponizing it, but I hope that never happens)

It's probably so the beam can be fired at a beam of hydrogen, as in a particle accelerator.
