Development of a 3-D energy-momentum analyzer for meV-scale energy electrons
S. Karkare, J. Feng, J. Maxson +1
In this article, we report on the development of a time-of-flight based electron energy analyzer capable of measuring the 3-D momentum and energy distributions of very low energy (…

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…
