Abstract

This project has characterized the bulk emission properties of carbon nanotube (CNT) forest cathodes fabricated with varied geometries. The overall goal of the project has been to evaluate CNT forest cathodes as a potential replacement for thermionic cathodes currently used in accelerator systems.
