Seminar DPPT: Martina Mrkvičková

We cordially invite you to a Department of Plasma Physics and Technology seminary lecture. The speaker is Dr. Martina Mrkvičková from the Plasma Diagnostics and Modelling research group and Didactics of Physics.

Martina Mrkvičková – Measurements of the electric field in APTD: four methods match

Abstract:

The electric field is one of the essential plasma parameters which determines the discharge dynamics and initiates chemistry in the plasma. Different experimental methods have been developed and applied for electric field determination. Yet, with such a variety of discharge types, gases, and other conditions, there is usually only one method matching the requirements of the studied discharge system. Our work aims to investigate several experimental methods for the determination of the electric field development and compare their results obtained under the same discharge conditions. The object suitable for all methods was a weak microseconds-lasting atmospheric pressure Townsend discharge (APTD) operated in the dielectric barrier configuration in pure nitrogen.
