A proton burst procedure a procedure devised whereby bursts of protons from a starship's sensor array were directed the warp core as a means of preventing the loss of antimatter.

In 2372, such a procedure was utilized aboard USS Voyager, which found itself loosing antimatter. It was found that the procedure caused significant hull stress and would have caused extensive damage if its structural integrity was not reinforced. Magnetizing the hull was a method of reducing the impact. The vessel's sensor array could not be used during the procedure. The vessel was ultimately heavily damaged by bursts generated by a duplicate of Voyager occupying the same spacetime location as a result of a spatial scission. (VOY: "Deadlock")
