Abstract :
In this work we present a carbon nanotubes electron source assembled with a low cost technique. We used a carbon nanotube cathode that reached the remarkable current density of 0,6 A/cm2. The cathode has been assembled with an external grid in a compact electron source that achieved a maximum output current density of 45 mA/cm2. This represents one the first examples of a CNTs electron source realized with a low cost assembly.
