Abstract: Future electron accelerators require DC high voltage photoguns to operate beyond 
the present state of the art to conduct new experiments that require ultra-bright electron 
beams with high average current and higher bunch charge. To meet these demands, the 
accelerators must demonstrate improvements in a number of photogun areas including vacuum, 
field emission elimination in high voltage electrodes, and photocathodes. This work illustrates 
how these improvements can be achieved by the application of suitable thin-films to the photogun 
structure for producing ultra-bright electron beams. The results are promising to meet the 
challenging requirements of high-average current electron sources.
