Developed by Dr. Egon Spengler and Dr. Ray Stantz after their residencies at Columbia University, the proton pack fires a stream of protons via a wand for use in paranormal investigation and capture. The protons, sometimes referred to as positrons, attack the negative ectoplasmic energy of a ghost, snaring the little bugger, holding it in place ideally above a trap.
The pack's beam creates a powerful recoil, and has damaging effects on material, usually combing to create extensive collateral damage. Early attempts to power the pack by wall current resulted in melted wiring. Instead, the pack is powered by...
an unlicensed mass of nuclear material with a half life of 5,000 years. Should the power source reach a critical thermal state, the resulting blast would affect half a square block.
The wand has controls for beam intensity, length, and polarization levels, with a maximum frequency adjustable to 500,000 Mhz. Crossing the streams from one or more wands was initially discouraged, as it was believed that "total protonic reversal" would occur; this effect would have catastrophic results, namely "the end of all life as we know it, and every molecule in one's body exploding at the speed of light."
