Abstract
Carbon-carbon grids for ion optics sets are thermomechanically stable under the extreme temperature changes that are experienced in ion thrusters. Screen, accelerator and decelerator grids are thermomechanically stable, lightweight, and resistant to erosion from ion sputtering and have extended lifetimes over conventional molybdenum grids.
