Field emission microscopy of carbon nanotube fibers: evaluating and interpreting spatial emission
Taha Y. Posos, Steven B. Fairchild, Jeongho Park +1
In this work, we quantify field emission properties of cathodes made from carbon nanotube (CNT) fibers. The cathodes were arranged in different configurations to determine the effe…

Work Function Characterization of the Directionally Solidified LaB6 VB2 Eutectic
Tyson C. Back, Steven B. Fairchild, John Boeckl +5
With its low work function and high mechanical strength, the LaB6/VB2 eutectic system is an interesting candidate for high performance thermionic emitters. For the development of d…

Laser Stimulated Grain Growth in 304 Stainless Steel Anodes for Reduced Hydrogen Outgassing
D. Gortat, M. Sparkes, S. B. Fairchild +6
Metal anodes in high power source (HPS) devices erode during operation due to hydrogen outgassing and plasma formation, both of which are thermally driven phenomena generated by th…
