Abstract
Carbon-carbon elements for ion optics sets are thermomechanically stable under the extreme temperature changes that are experienced in ion thrusters. The elements described include screen and accelerator grids and methods of producing such grids. The described elements are thermomechanically stable, lightweight, and resistant to sputtering.
