- Abstract:
- The ion energy distribution in the plasma exhaust plume of a hall thruster is important to evaluate the influence of the hall thruster plume and optimize the thruster position on the spacecraft. Retarding potential analyzer (RPA) had been used to measure the ion energy distribution at a certain location downstream of the low-power hall thruster at various status. These experimental results indicate that the hall thruster plume is comprised of both low energy charge exchange (CEX ) and high energy source ions. The high energy ions distribution is mostly at the center line of the thruster, the low energy ion distribution firstly increases and then de
