Proton pack

Fictional device

The proton pack is a fictional energy-based capture device, used for controlling and lassoing ghosts in the Ghostbusters universe. First depicted in the film Ghostbusters, it has a hand-held wand connected to a backpack-sized nuclear accelerator. It controls a stream of highly focused and radially polarized protons that electrostatically controls the negatively charged energy of a ghost, allowing it to be held in the stream.
