Abstract :
We report detailed modeling and simulations of secondary electron generation, transport, and emission from diamond cathodes. The simulations can explain the range of experimentally determined emission probability as a function of external electric field. It is essential to include conservation of transverse momentum and effective mass anisotropy when modeling emission.
