|Advanced project shows in detail how to utilize a micro-wave oven to construct a powerful source of directional microwaves. These plans are written with detail given to the mathematical equations necessary to design the horn antenna. This project can be a tremendous study aid in the field of high power microwaves. Unfortunately it should only be attempted by those familiar with high voltage and high power radio frequency circuits. All strategic parts are available through us on a special request. You must make contact to verify age and identity.|
The Mass Launcher fires a 4-ounce projectile to a velocity capable of splitting a 1 x 2" pine board on impact.
A lighter projectile can be fired at considerably higher velocity. Device uses stored electrical energy accumulated on a capacitor bank and switched into the accelerator coil by a special three terminal triggered spark switch. The accelerator coil induces a very high amperage current in the projectile that now sets up its own magnetic field that opposes that in the coil causing a repulsive moment of accelerative force on the projectile.
The Mass Launcher uses a flat spiral coil arranged with a vertical flyway and wooden support base. The projectile used is on the heavy side weighing in at over 4 ounces. Its geometry is a flat aluminum washer that is of the same size as the coil. This geometry provides maximum coupling and optimizes electric to kinetic efficiency. Initial velocity is over 300 fps but quickly drops off due to the poor aero dynamics of the projectile shape. A piece of 2 foot long 2 x 1 inch pine board placed on the flyway tube will be easily split by projectile impact.
Projectile may be retained on a flyway for repeating display or free flying.
The Mass Launcher module requires our HEP50 Pulser/Ignitor (which includes a charger, capacitor bank, and trigger) or similar.
|Coil Gun Pistol|
Danger: will cause injury or break objects at close range.
Fascinating project propels aluminum rings to a considerable velocity. Demonstrates the LORENTZ force plus important properties of magnetic energy. Rings may be restrained to flyway for safety or classroom demonstration. Adult supervision usually not required for outside use. Operates from 8AA batteries that slide into hand grip. Can be easily modified to propel ball bearings.

|Plasma Thermal Gun|
The PPRO1 Plasma Thermal Gun utilizes the electrothermal energy obtained from vaporizing a metallic material, creating a pressure wave of sufficient magnitude to cause a projectile to accelerate to ballistic velocities.
The system shown on our data is a relatively low velocity device within the building capability of most hobbyists. The project may be scaled up for serious research with an obvious increase in high voltage handling and ballistic hazards. The project requires experience in the handling of high-voltage, high-energy devices.
Operation requires a high-energy pulser such as our HEP50, which is shown using a 5Kv Capacitor Bank. These values may be altered within limits to allow the use of available capacitors that you may have on hand.
An energy-storage capacitor is charged from a programmable, controlled current source to a selected high voltage. This capacitor is switched by a triggered spark gap, dumping all the stored energy into a small-volume explosion chamber and vaporizing a thin, aluminum wire placed inside the chamber. A pressure wave forces a projectile out of the barrel to a high velocity.
This project is suitable for a science class demonstration if properly supervised with qualified personnel.
Plasma Thermal Gun Assembly Parts are Fabricated by Builder from Readily Available Materials.
This system as sold will require proper enclosures and must be installed by qualified personnel if used for public demonstrations and displays.
