Ghostbusters Rely on Clippard

Category: 

The Proton Pack is a piece of particle accelerating machinery created by Egon Spengler and used by the Ghostbusters. It is their primary tool in the 1984 & 1989 Ghostbusters films for "busting" ghosts. It has a hand-held wand ("Neutrona Wand" as scripted by Dan Aykroyd) connected to a backpack-sized cyclotron. The theory is that it fires a 'semi-controlled' stream of protons that neutralizes the negatively charged electromagnetic radiation of a ghost allowing it to be held in the active stream.  This systems rely on the high quality and reliability that Clippard provides.  Some products used are the R-701 regulator, the R-341 Delay valve and several other brass fittings and tubing.



The props representing proton packs were created by the prop department at Columbia Pictures. They are made of molded fiberglass shells on aluminium backplates (or "motherboards") bolted to military surplus A.L.I.C.E. pack frames. The basic shape was sculpted from foam; later, a rubber mold was made, from which fiberglass shells were pulled. The "wand" had an extending barrel mechanism and the electronics were quite advanced for the time. They were then finished with various surplus 1960s resistors, pneumatic fittings, hoses and ribbon cable, as well as surplus warning labels and custom-made metal fittings. The overall weight of these props is said to be around 35lbs. The "hero" props were substituted in stunt scenes by flimsy foam rubber pulls from the same mold. The proton packs have a lightbar with 15 blue scrolling lights in a box on the left-hand side and 4 red lights in the circular "cyclotron" portion of the bottom of the prop that light up in rotation. The "wand" also featured numerous light features; the most elaborate versions had fluorescent bargraphs, incandescent bulbs, and strobing flashes in the tip for the visual effects crew to synchronize the famous 'streams'.
