Tunability of the THz space-charge modulation in a vacuum microdiode
P. Jonsson, M. Ilkov, A. Manolescu +2
Under certain conditions, space-charge limited emission in vacuum microdiodes manifests as clearly defined bunches of charge with a regular size and interval. The frequency corresp…

Space-charge modulation in vacuum microdiodes at THz frequencies
Andreas Pedersen, Andrei Manolescu, Agust Valfells
We investigate the dynamics of a space-charge limited, photoinjected, electron beam in a microscopic vacuum diode. Due to the small nature of the system it is possible to conduct h…
