An air-assisted passive ionizer is developed for the elimination of static charges on charged particles accumulated in pipes, hoppers, or silos. The ionizer is a grounded electrode with a sharp tip at which corona discharge takes place due to the electric field produced by the charged particles. A charged plastic pipe was used to test the performance of the passive ionizer. The ionizer was placed...
Corona discharge plays an important role in industrial and commercial applications, especially for large-area corona discharge need. It is a common method for the electrets industry. Nevertheless, achieving uniform charge distribution of the large area electret films is difficult. In order to achieve uniform surface charges distribution in large plane, the multi-pin-grid-plate electrode system which...

Surface charging on insulators in vacuum is recognized as one of the important phenomenon related to the occurrence of vacuum surface discharge events. In order to understand the vacuum discharge phenomenon deeply, it is necessary to investigate the influence of the surface charges on surface discharge events. Therefore the research on surface charges on an insulator is requested to measure the charge...
It is said that surface charging on insulator has an influence on vacuum surface discharge. To clarify mechanism of that event, it is necessary to investigate the progress of surface charge distribution on insulator during voltage application. In this research, real-time measurement of surface charge distributions on insulators (Alumina plate and PET film) in vacuum under AC voltage application was...
