Carbon Fiber Velvet Cathodes Generating Powerful Electron Pulses Via Field Emission

Our Cathode is composed of a carbon fiber velvet, providing a means of generating powerful electron pulses by field emission from the tops of the carbon fibers.

These devices have been used by numerous customers from varying industries. For example, discrete-fiber emitters, utilizing several (or even one) individual carbon fibers, have been developed for use by researchers. Additionally, the device has also been used by the Air Force Research Lab, the Naval Research Lab, Raytheon, Lawrence Livermore National Laboratory, and BAE Systems Bofors AB.

The US-designed and produced Cathodes can be customized for different applications including the generation of microwaves, x-rays, and laser radiation. They can be fabricated in a wide variety of physical configurations, ranging from simple planar and cylindrical forms to more complex lobed shapes. The device can be provided on a metallic or graphite substrate.
