The Technical University of Applied Sciences Mittelhessen (THM) in Gießen is the birthplace of the radio frequency ion thruster, a groundbreaking technology in space travel. However, the benefits of electric propulsion extend beyond space, offering numerous advantages here on Earth. Dr. Andreas Reeh, a former THM student, is currently developing components to further enhance the precision and efficiency of this technology. In particular, this advancement holds great potential for the fields of optics and semiconductor technology, opening up new possibilities for innovation and progress.

Ion propulsion: A revolutionary technology for precise space maneuvers
The ion thruster, a revolutionary technology in space travel since the 1960s, eschews the need for large amounts of chemical propellant by generating a propulsion beam from ions, utilizing electronic components and a small amount of gas. This lightweight yet durable and reliable force enables precise maneuvers in outer space. The Research Group for Spacecraft Electronics at THM is dedicated to advancing this technology, pushing the boundaries of what is possible in space exploration.
Dr. Andreas Reeh revolutionizes surface processing with ion thrusters
During his doctoral studies at THM, Dr. Andreas Reeh focused on the modeling and simulation of radio frequency ion thrusters. He recognized the potential to apply this technology in high-precision surface machining. While the current ion beam sputtering process is already used in the optical and semiconductor industries, Reeh believes there are still opportunities for optimization. His concept, which is purely electronic compared to the conventional mechanical matchbox, allows for a more precise and repeatable adjustment of the ion beam current. This results in a reduced error rate, more accurate material processing, faster processing times, and increased reliability. Furthermore, it opens up new processes and facility designs.
ESA Provides Financial Support for Optimization of Radiofrequency Ion Thrusters
The European Space Agency (ESA) recognizes the potential of optimizing the Radio Frequency Ion Thruster and provides financial support to Dr. Andreas Reeh’s company. Through the “ESA Spark Funding,” the transfer of technology from space to terrestrial applications is promoted. Additionally, the company receives incubation support at “ESA BIC Hessen.” This support enables not only the development of devices for industrial applications but also the further development of the company’s commercial aspects.
Dr. Andreas Reeh focuses on analyzing potential customers and optimizing his product
Dr. Andreas Reeh is currently analyzing potential customers in the market and working on further optimizing his product. The devices are mostly manufactured through contract manufacturing, with Dr. Reeh himself handling the final assembly. However, in the future, he will require someone to take care of the business aspects of his company so that he can fully focus on development.
Advancing Space Exploration: Optimizing Radio Frequency Ion Thrusters
The optimization of the radio frequency ion thruster and its application in surface processing offer numerous advantages for space travel and semiconductor technology. Dr. Andreas Reeh’s work at THM and the support from ESA enable the further development of this technology and the maximization of its efficiency. With more precise material processing, reduced error rates, and increased reliability, a wide range of applications is opened up for this innovative technology.
