Whereas traditional rocket systems must carry large amounts of fuel to generate sufficient propulsion, electric propulsion systems use an electric field to accelerate small particles to high velocities and launch them from thrusters at extremely high velocities. This high discharge velocity greatly reduces the amount of fuel required. This property of ion thrusters makes them ideal for correcting the position of satellites.
Although ion thrusters produce relatively low thrust relative to conventional propulsion systems, they are capable of producing uninterrupted propulsion for months at a time. This allows for constant acceleration for the propelling spacecraft. Another special feature compared to conventional rocket propulsion systems is that ion thrusters only work in space or in a vacuum.
Therefore, when testing the performance of ion thrusters during development, it is necessary to create conditions similar to those in space. This requires a test system that can generate the same stress conditions as in space. It is believed that such a system must be able to ensure that the thrusters can continue to simulate the environment in space when operating at maximum thrust.
