The Taser Cannon can direct a 15,000 Ampere plasma channel through the air along a straight trajectory, at grounded targets up to 35 ft downrange. The cannon consists of 30 high pressure pneumatic dart stations, each capable of launching a tapered aluminum sabot that trails a thin 'seed wire' 0.008 inches in diameter. Cannon tilt and pan is pneumatic, and a sighting laser is located inside the cannon head. When a launched sabot contacts the target, the Marx-configured capacitor bank automatically fires and erects the bank to 110,000 volts, igniting a plasma channel along the vaporized seed wire. The plasma channel quickly intensifies, magnetically confined in the air by the Lorentz forces of its own current. Damage to the target can vary widely. Most spectators experience some degree of sinus discomfort after several firings, due to the high brissance of the plasma explosion. The capacitor bank is currently disassembled, and newer capacitors are being added to increase the bank energy to 250 kilojoules, and the range to 50 feet.
