The Proton Pack is the primary ghost capturing device used by the Ghostbusters.
Designed in 1984 by Egon Spengler and Ray Stantz, the Proton Pack counters the negative energy which ghosts are made of with a Proton Stream, a stream of positively charged ions which can harness a ghost. The Proton Stream is very dangerous and barely controllable. Egon has also mentioned that crossing Proton Streams will result in total protonic reversal causing all life as we know it to stop instantaneously and every molecule in a user's body to explode at the speed of light.
The Proton Packs are nuclear powered. The power cells of the Proton Pack have a half life of 5,000 years.
