Elementary Processes in Gas Discharges

We study the elementary processes in gas discharges through a mix of theory, modeling and the development of diagnostics.

[Translate to English:]

As much as we enjoy exploring new fields of application, our research has always been based on one underlying interest: the elementary processes in and the physics of plasmas

In the EPG group, we use our thorough understanding of elementary processes to develop predictive models of a large range of plasmas. These models take into account the intensity and effectivity of processes such as ionization, recombination, transport, radiation, excitation, de-excitation, chemical reactions and surface processes.

We integrate state-of-the art plasma diagnostics (imaging, passive and active spectroscopy) and advanced plasma models that enable plasma users to optimize the plasma source for their specific application. Over the years, the group has worked on a wide range of applications: plasma etching, lighting, medical applications and so much more.

Research Areas

Meet some of our Researchers


Check out all our courses

Are you a student interested in doing a BEP project or graduating in the EPG group? There are ample traineeship opportunities for students within our group. In experimental projects you will familiarise yourself with one or more of the passive or active plasma diagnostics that we have available. It is also possible to work on theoretical subjects, ranging from plasma fluid modelling to atomic-scale Monte Carlo simulations. In all projects you team up with one or more of our PhD students and staff members. You are a full member of such research team and will get a flavour of state-of-the-art plasma research.

If you are interested, please contact one of our PhD students or staff members



In order to understand and improve plasmas, we are using a blend of experimental and theoretical/numerical techniques:

Imaging and passive spectroscopy

The most straightforward optical techniques that can be used for plasma diagnostics are optical imaging and emission spectroscopy.

Active spectroscopy

Apart from investigation the emission properties of plasmas more direct information can often be obtained by laser diagnostics.

Modelling and numerical simulation

By carrying out experiments, you can gather all kinds of information about the plasma, like its electron temperature and density, its rate of emission of radiation of a particular wavelength, and the like.

Within our EPG group we work on all kinds of medical applications of plasma. Through Plasmacure we have compelling evidence that this plasma technology has a right to exist in the medical world and can be used safely in a clinic. That in turn helps us with funding for other studies of this type. We have a very cordial cooperation with Plasmacure. Bas knows how to get things done that I - if you had told me 5 years ago - would never have believed.
