alteração de carga com o uso de radiação ultravioleta

摘要

A system(109) for altering charge of a dielectric material (90) uses ultraviolet radiation. The system includes a gas source (102) and an ultraviolet radiation source (104). The gas source (102) introduced a gas (103) to a region adjacent the dielectric material (90). The ultraviolet radiation source (104) is arranged to irradiate the region to adjust charge on the dielectric material. A method of altering charge on a dielectric material (90) is also disclosed in which a gas (103) is introduced to a region adjacent the dielectric materia (90)1. The region is then irradiated with the ultraviolet radiation (105) to alter charge on the dielectric material (90).
