BURFIT-80 RF Ion Thruster is tested.

The prototype radio frequency ion thruster (BURFIT-80) is successfully tested inside the BUSTLab vacuum chamber. The thruster has an 80 mm diameter discharge chamber and operates at 13.56 MHz radio frequency. Grid voltage differences of up to 1500 V were provided to the thruster during its initial tests. This earliest prototype has 91 extraction holes only. Improved, denser grid systems are going to be tested in the near future.
