Vacuum insulation of a large negative ion source for fusion application is experimentally examined, which is characterized by large-area grids with multiple-apertures. The experimental results showed that sustainable voltages were found to be dominated by the electric field profiles generated around the apertures and grid area. These empirical laws are applied to the modification of the ion source.
