A One-Step Model of Photoemission from Single Crystal Surfaces
Siddharth Karkare, Weishi Wan, Jun Feng +2
In this paper, we present a 3-D one step photoemission model that can be used to calculate the quantum efficiency and momentum distributions of electrons photoemitted from ordered…
Near atomically smooth alkali antimonide photocathode thin films
Jun Feng, Siddharth Karkare, James Nasiatka +3
Nano-roughness limits the emittance of electron beams that can be generated by high efficiency photocathodes, such as the thermally reacted alkali antimonide thin films. However th…
Ultrafast laser pulse heating of metallic photocathodes and its contribution to intrinsic emittance
J. Maxson, P. Musumeci, L. Cultrera +2
The heating of the electronic distribution of a copper photocathode due to an intense drive laser pulse is calculated under the two-temperature model using fluences and pulse lengt…
