A primary ignition system for large caliber ammunition which ignition system is less sensitive to unwanted ignition by conventional temperatures or conventional electrical signals or by stray electrostatic voltage electrical signals, or stray RF frequency signals. This ignition primer device begins the ignition sequence with applying a high voltage electrical pulse to a non-energetic element, specially coated with nano sized aluminum particles, to release and ionized discharge that generate a plasma in order to ignite an environmentally friendly ignition composition mix. The ignition composition is also comprised of aluminum water based nano material combined with oxidizer and binder. In the device's primer head assembly is a brass ignition pin pressed into a (non-electrically conductive) Torlon&#xae; material cup. The non-conductive Torlon&#xae; material acts as an insulator for the entire system.

Low energy ignition system for large and medium caliber ammunition

A pulse signal generator apparatus for producing an ultrafast, high-voltage pulser using a circumferentially illuminated, laser-switched radial transmission line transformer. The apparatus includes a radial transmission line transformer having a circular plate structure which can be coupled to a voltage source that becomes conductive upon the application thereto of a predetermined type of light energy. A laser switching device which is integral with the radial transmission line transformer and surrounds the circular plate structure, operates to switch an input electrical pulse of a predetermined peak voltage, injected at a circumferential edge of the circular plate structure onto a peripheral surface of the circular plate structure, to produce an output electrical pulse having a substantially higher peak voltage than the predetermined peak voltage of the input electrical pulse, at a center of the circular plate structure of the transmission line transformer. The apparatus also includes a laser for producing the predetermined type of light energy which illuminates the laser switching device.

Ultrafast, high voltage pulser using circumferentially illuminated,

The present invention describes a method of explosively vaporizing a piece f semiconductor material in a plasma formed by a fast, high voltage current pulse. The semiconductor material may be formed from crystalline, polycrystalline, or amorphous forms of semiconductor material. After the semiconductor material is vaporized, it coalesces as the plasma begins to cool and is deposited in a collection system. The size and composition of the microparticles formed by this process can be controlled by conditioning the plasma in predetermined manners. In particular, impurities can be introduced either in the target material, in gas introduced in the plasma, or in the gas through which the coalescing microparticles travel prior to deposition.
