Abstract

A novel Ion head architecture is presented for high resolution Ionographic printing, with a spot size capability of ∼50 μm. This ion head is manufactured using electroforming technology to provide a unique discharge geometry including a controlled gap which may be tailored to the discharge. Experimental measurements confirm the advantage of this geometry in producing high current densities. An electroformed screen electrode is also provided to focus the ion beam on a small spot. Experiments using a novel knife edge technique validate the achievable spot size. A simplified numerical and analytical model based on Paschen's curve shows the effect of nozzle scaling on the charge that may be extracted a nozzle. The model also allows testing the effect of an optimized nozzle profile demonstrating its advantages for a small nozzle implementation. The knife edge tool is used to experiment with different discharge electrode nozzle sizes for a fixed screen electrode allowing selection of the most efficient combination.
