Dekyon
From Star Trek : Freedom's Wiki
A dekyon is a subatomic particle with subspace qualities. Dekyons can be emitted through a starship's deflector dish via a dekyon beam. The projection of a dekyon beam over a distance of 50 million kilometers requires a great amount of energy.
In 2371, the USS Voyager used a dekyon beam to widen a rip in a quantum singularity to escape it. (VOY: "Parallax")
