离子推力器的束流分布,直接影响离子推力器离子光学系统(亦称栅极组件)的性能和寿命。通过对离子推力器离子光学系统的改进和放电室磁场的优化,使束流均匀性系数R值达到0.7左右。离子推力器束流分布均匀性的有效提高,有助于改善离子光学系统的受热分布,降低离子光学系统的温度,并能减小其温度差,使离子光学系统的热应力和热变形降低,进而延长离子推力器的寿命。
Ion thruster beam distribution, a direct impact on ion thruster ion optical system (also known as gate components) performance and life expectancy. Through the improvement of the ion optical system of the ion thruster and the optimization of the magnetic field in the discharge chamber, the beam uniformity coefficient R value is about 0.7. The improvement of ionosphere beam current distribution uniformity can help to improve the heat distribution of ion optical system, reduce the temperature of ion optical system and reduce the temperature difference, so as to reduce the thermal stress and thermal deformation of ion optical system, Thus prolonging the life of ion thruster.
