2021-09: Plasma Demonstrator

The Deutsche Museum in Munich established a new site in Nürnberg. The Deutsche Museum in Nürnberg opened its gates in September 2021. For this new museum we designed, manufactured, and installed a plasma demonstrator. Visitors can start the plasma just by pressing a knob. It is an RF driven inductively coupled plasma which ignites a gas in a glas body. The demonstrator has magnets that can be moved and by that influence the plasma density. While visitors move the magnets they can observe the plasma brightness change.

The glas body and experience with a former plasma demonstrator was contributed by Forschungszentrum Jülich. This we much appreciated.

2017-2021: RF Modules for Wien Filter

The Cooler Synchrotron COSY at the Forschungszentrum Jülich is a medium energy accelerator and storage ring which is considered a unique worldwide facility for spin Physics. The JEDI Collaboration operates COSY as part of its activities aiming for the measurement of the Electric Dipole Moments (EDM) of Deuterons and Protons. The EDM is a new fundamental property of particles shall provide an answer of our very existence. To do so, JEDI in collaboration with the Institute of High Frequency Technology of the RWTH Aachen developed a novel accelerator component, the waveguide RF Wien Filter, for spin manipulation while maintaining a vanishing Lorentz force. For this exciting research project we provided a variety of RF modules: variable resistors, voltage/current detectors, RF isolators and transformers. The most sophisticated piece of equipment we designed, manufactured, and delivered was a unique ultra-fast and high power RF switch. For more information on the Wien Filter see the following papers:

2014: Electrical Asymmetry Effect

The target of this unique plasma system was to generate a customized voltage waveform at the systems electrodes. For this three RF Generators worked on consecutive harmonic frequencies by using an external signal source. This signal source not only provided the three phase locked frequencies but it also allowed to control the phase differences between all three of them. All three channels have an own matching network in order to allow individual matching and by that high efficient operation. RF Generators and MatchingNetworks we equipped with specific filters in order to work independently in each channel. This project we realized for and with Dr. Julian Schulze and his team at the West Virginia University.

2010: RF Generator for ISS

For and together with the Max Planck Institute for Extraterrestrial Physics we designed and manufactured RF Generators. Each RF Generator contains two independent channels. Each channel delivers a 81.36MHz signal with a maximum output power of 5 Watts. The focus we put on exact power control and a light weight package. With it an ICP application is supplied to research Dusty Plasma in a non gravity environment. For more technical information please visit: NASA: Dusty Plasma Research on ISS.
