Proton Pack

The Proton Pack is a fictional piece of nuclear accelerative machinery used for weakening ghosts and aiding in capturing them it has a hand-held wand ("Neutrona 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.
The Proton Pack is a man-portable particle accelerator system that is used to create a charged particle beam - composed of protons - that is fired by the proton gun (also referred to as the "neutrona wand"). a "positron collider", and presumably functions by colliding high-energy positrons to generate its proton beam. The positive electric charge of the proton beams allows a ghostbuster to contain and hold "negatively charged ectoplasmic entities". This containment ability allows the wielder to position a ghost above a trap for capture. the accelerator system operates similarly to a cyclotron "unlicensed nuclear accelerators". modern particle accelerators produce well collimated particle beams. This is far different from the beam from a Proton Pack, which tends to undulate wildly (though it still stays within the general area at which the user is aiming). The proton stream is quite destructive to physical objects, and can cause extensive property damage.
; the energy emitted by the Proton Stream helps to dissipate psychokenitic (PK) energy which ghosts use to manifest themselves. Draining them of their PK energy weakens them, allowing them to be captured in their portable ghost traps.
each pack's energy cell has a half-life of 5,000 years. Knobs on the main stock of the Proton Pack can perform various functions to customize the proton stream, including adjustments for stream intensity, length, and degrees of polarization. the maximum power setting for the Proton Packs is "500,000 Mhz," which possibly refers to the rate of positron collisions occurring within the pack's accelerator system.
