Mature Technology

The IFM Nano Thruster is a mature technology, developed under ESA contracts for 15 years. In this time more than 100 emitter have been tested and an ongoing lifetime test has demonstrated more than 13.000 h of firing without degradation of the emitter performance.

Dynamic precise Thrust control

The thrust can be controlled through the electrode voltages, providing excellent controllability over the full thrust range and a low thrust noise.

Controllable specific impulse up to 5000 s

Due to the efficient ionization process which allows to ionize up to 60% of the evaporated Indium atoms, the IFM Nano can provide a higher specific impulse than any other ion propulsion system currently on the market.

Redundant neutralizer cathodes

As the IFM Nano thruster expels an ion current of up to 3 mA, the module needs means to prevent spacecraft charging. This is achieved by the use of two cold-redundant electron sources acting as neutralizers. Such an electron source consists of a Tantalum disc which is heated up to 2,200 K and biased to -200 V. Once electrons have left the neutralizer, they will be pulled towards the positive potential of the ion plume. The PPU is able to measure and control this charge balancing electron current.

Safe and Inert System compliant with all Launcher Requirements

The IFM Nano contains no moving parts and the propellant is in its solid state at room temperature. Avoiding any liquid and reactive propellants as well as pressurized tanks significantly simplifies handling, integration and launch procedures.
