The most recognizable part of the Proton Pack has to be the Cyclotron. Dan Aykroid hand a hand in designing all of the Ghostbusters equipment for the film. The Cyclotron on the proton pack is based on a real physics concept (Cyclotron physics). When designing props, it really helps to understand what the prop is based on in real world items.

For this build I used pages 2 and 3 of the Stefan plans (Page 2, Page 3).
