Advancement in single-atom layer graphene coatings improves accelerator electron source lifespans

Caption

The image of the graphene layers on the photocathode shows areas of low quantum efficiency (in blue) where no electron transmission occurs. The red and yellow areas show increasingly high quantum efficiency. Photoelectrons are emitted and transmitted through the graphene in those areas while overall the material is protected from corrosive gases produced.
