Abstract :
To evaluate the effects of inflowing-high-energy electrons on the grid erosion, three-dimensional full-PIC analyses of ion engine were conducted. A comparison of the results of full-PIC results show that the inflowing high energy electrons expand the sheath region downstream and blurs the sheath edge. However, only a slight influence of the electrons on grid currents is observed.
