An accelerator grid is sputtered due to impingement of charge-exchange ions. The erosion of the grid limits the normal operation of the microwave discharge ion engine, in which long life and high reliability are inherent because of electrode-less plasma generations. We measured aperture shape of C/C grid after 20,000 hour endurance test. This measurement method was using a digital microscope. This paper reports measurement techniques and results of aperture shape.
