Program of the International School on Low Temperature Plasma Physics and its Master Class 2023

In 2023, the 26th International School on 'Low Temperature Plasma Physics: Basics and Applications' (30.09.2023 - 05.10.2023) and its Master Class 'Advanced diagnostics of atmospheric pressure plasmas' (05.10.2023 - 07.10.2023) will take place at the Physikzentrum Bad Honnef (Germany).

Program of the School

We are looking forward to it because, once again, we are putting together a very promising program, with the support of many colleagues who are willing to give a talk at the School.

12:30	Lunch
14:00	Modelling: Hands on a Boltzmann solver Luis L. Alves, Antonio Tejero (University of Lisbon, Portugal) Attendees will be given the opportunity to perform a series of exercises, analyzing the evolution of the EEDF in different atomic and molecular gases, with variations in the applied electric field (amplitude and possibly frequency) and/or in the populations of vibrationally / rotationally excited states. A comparison between calculated and measured swarm parameters will also be proposed. The workshop is very interactive, with plenty of questions / discussions taking place, focusing on both physical and numerical features.
14:00	Experimental Workshop I - Basics of laser absorption spectrocopy Olivier Guaitella (LPP, Ecole polytechnique, France) The objective of this experimental workshop is to shed light on some difficulties and pitfalls that may be encountered when using plasma diagnostics tools. Real examples are going to be experienced using a DC plasma reactor. As the simplest possible plasma discharge, it should allow relatively easily to obtain basics parameters such as electric field, gas temperature, and densities of main species. Along the workshop, we will illustrate that even in the simple conditions of a low pressure DC glow discharge in Argon, large errors can be made if things are not carefully done. The main diagnostic tool will be tuneable laser diode to perform absorption spectroscopy. Tunable laser absorption spectroscopy will be used to assess Ar (3P2) metastable state density, but also the gas temperature. Besides the presentation and fine description of all parts of the experiment, attention will be paid to the optical alignment, the optical saturation effect, and various possible traps
14:00	Hiking Possible destinations can be requested from the organization team
14:00	Experimental Workshop II Sebastian Burhenn, Sylvain Iseni (Ruhr-Unversität Bochum, Germany; GREMI, France) In the Experimental Workshop II two maybe three so called active investigation tools are covered. The objective of this experimental workshop is to give the attendees a first insight into the technical aspects including some difficulties and pitfalls that may be encountered when using optical emission spectroscopy (OES) as plasma diagnostics tool. For this we will go down to the basics and we will setup our own spectrographs. For this we will have to discuss the influences of the dispersing element. Answer questions: What are these slits for? Do we have to think about them? Try to wave length calibrate our systems Compare our home-made to modern so called USB spectrographs Interpret the emission spectra of some selected light sources by use of analysing software. (maybe) apply our diagnostics to the DC plasma reactor of the alternative experimental workshop. A brief reminder of the requirements for OES and the consequences for the actual instruments will be given first.
