Abstract:

We propose a carbon nanotube based cold cathode designed for high current density, continuous beam operation for Traveling Wave Tubes and other microwave device applications. Our approach in this proposal will be to design the CNT emitters to spread the emission current load and to heat sink the emitters firmly to high thermal conducting carbon fibers. The carbon fiber substrate will also be used to align the carbon nanotube emitters and space them apart such that they will not electrically shield each other. Feasibility of this approach will be demonstrated by achieving 1-10 Amps/cm2 current density in continuous beam operation with a uniformity of 20% across the cathode face.
