Abstract

We fabricated a prototype of an e-beam irradiator which is low energy and diode type by using sprayed double walled carbon nanotubes (DWCNTs). The diode type e-beam irradiator consisted of a grounded e-beam window which was made of thin Havar foil and a negatively charged cathode where carbon nanotubes were sprayed on titanium coated aluminum rod. Synthesized DWCNTs which were purified through the chemical processes and then mixed with ethanol were sprayed several hundred times on the surface area of 2×300 mm². A phosphor screen located on the e-beam window and a CCD camera was used to observe the emitted electron beams directly from the cathode to the air with an increase of the voltage. The measured e-beam current was 1.5 mA at -95 kV.
