<p>A fluid jet asisted ion projection and printing apparatus wherein substantially equal numbers of positive and negative ions are generated simultaneously during a series of RF arc breakdowns (48,50) which take place within a fluid transport channel passing through the body of the apparatus. The rapidly moving fluid stream, passing through the channel transports the ions which may be allowed to pass out of the body (26) or may be neutralized within the body by ion modulation electrodes (92) within the channel. Ions of a selected sign may be accelerated toward and deposited, in an imagewise pattern, upon a relatively moving charge receptor (86).</p> |
