Advanced Practical Excersise

Microplasmas (401)

In this experiment a micro-atmospheric pressure plasma jet is examined and applied for simple surface modifications. Such modifications, e.g. In the wettability are made possible by the admixture of molecular components such as, for example, oxygen, which are dissociated in the plasma. Within the scope of this experiment the atomic oxygen density is to be determined by means of optical emission spectroscopy (actinometry) and correlations with resulting surface properties of samples (contact angle measurements) are to be investigated. The experiment thus provides a comprehensive overview of the physics and application of atmospheric pressure plasmas and is located at the interface between plasma physics, plasma diagnostics and surface physics.

This experiment is now available online!
