The performance of x-ray free electron lasers and ultrafast electron diffraction experiments is
largely dependent on the brightness of electron sources from photoinjectors. The maximum …

In this paper we report on the generation of cold electron beams using a Cs 3 Sb
photocathode grown by codeposition of Sb and Cs. By cooling the photocathode to 90 K we …

Nano-roughness is one of the major factors degrading the emittance of electron beams that
can be generated by high efficiency photocathodes, such as the thermally reacted alkali …

Abstract Very-high-frequency (VHF) gun photoinjectors, capable of producing high-
brightness and high-repetition-rate electron bunches, are some of the best electron sources …
