Název v původním jazyce

Dynamic Study of Fast Measurement with Langmuir Probe

Popis výsledku v původním jazyce

Probe measurement is one of the main techniques used to determine the plasma parameters, which are crucial to understand the plasma behaviour. There are many types of probes and the interpretation of the measurements can be very difficult. However, we aim to study the common Langmuir probes, where the determination of plasma parameters from volt-ampere characteristics is well understood under standard conditions. In the data analysis, it is assumed that the probe and the surrounding plasma are always in a steady state. This is easy to achieve with slow measurement, but if there is a need for fast data acquisition, we don&apos;t have a certain answer to what is the lowest possible time of measurement. We use a 2D3V particle-in-cell model of a cylindrical Langmuir probe to study the dynamic processes caused by a change of the probe potential. Our aim is to determine the stabilization time needed for fast measurements as a function of plasma parameters and probe potential.
