Proton pack Proton pack The proton pack is an energy weapon used for weakening ghosts and aiding in capturing them within the "Ghostbusters" universe. First depicted in the film "Ghostbusters", it has a hand-held wand ("Neutrona Wand" or particle thrower) connected to a backpack-sized particle accelerator. It fires a stream of highly focused and radially polarized protons that electrostatically traps the negatively charged energy of a ghost, allowing it to be held in the stream. The proton pack, designed by Dr. Egon Spengler, is a man-portable particle accelerator system that is used to create a charged particle beam—composed of protons—that is fired
