The Proton Pack is a fictional 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 ("Neutrino Wand" or particle thrower) connected to a backpack-sized particle accelerator. It fires a positively charged stream of protons that attract the negatively charged energy of a ghost, allowing it to be held in the stream while active.

Famous quotes containing the word pack:
“A favorite of outdoor alcoholics, connoisseurs and Fundamentalists, these pills turn water into wine. In 10 minutes the most fetid swamp scum in the forest can become modest red, elusive and light on first taste, yet playful—one might say a trifle impudent—on the afterbite. Saves pack space by eliminating need for bulky corkscrew, decanter and bottles. Store pills on their sides in a cool dark place.”
—Alfred Gingold, U.S. humorist. Items From Our Catalogue, “Wine Pills,” Avon Books (1982)
