Manufacturing

At SPL, various areas of manufacturing of advanced micromaterials are investiaged. A special focus is laid on novel, porous materials suited for emitter tip densification for future high current density emitters.

Silicon MEMS manufacturing

MEMS processes are investigated to manufacture high precision propulsion devices, providing high alignment accuracies and the ability to batch process propulsion components. This includes electrospray emitter packaging, and the extractor aperture grid.
