A coupled helicon/IEC plasma jet is in development for space propulsion applications. This device decouples the ionization and plasma acceleration process into separate stages. A realistic model is to consider a plasma media where the relative permittivity is negative or imaginary. ... Per saperne di più
This paper presents a three-dimensional fluid model for a low-power microwave-excited argon microstrip plasma source operated at 2.45 GHz. The gas pressures in the gas channel are 50 and 100 Torr and the input power is 2 W. Simulations are performed by the Plasma Module of COMSOL ... Per saperne di più
As part of the European Research Roadmap to the Realization of Fusion Energy [1], the Divertor Tokamak Test facility (DTT) [2] aims to study alternative divertor configurations in view of the EU-DEMO [3] power exhaust handling issues. The DTT superconducting magnet system comprises 18 ... Per saperne di più
The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates.
