摘要:
An improved modulation structure for the marking head of an ionographic marking aparatus for increasing the effective lifetime of the modulation electrodes in the highly corrosive atmosphere of such a device. A relative bias on the order of about 10% of the ion output cut-off bias is imposed across the ion modulation region in order to inhibit the deterioration effects of the ions on the modulation electrodes.
