To test ion engines, it is necessary to create conditions close to space on Earth. To do this, vacuum chambers of a sufficiently large volume are manufactured with a powerful pumping system, dispersion devices and protection against plasma flow.
For ease of maintenance and operation, the test engine is placed in a pre-chamber, which can be cut off from the main vacuum chamber.
