Prof. Bernhard Unterberg "Hotter than the Sun"
On November 3, Prof. Bernhard Unterberg will give a lecture on "Hotter than the Sun" as part of the "All Plasma" lecture series. This will take place at Blue Square starting at 18:00. Interested parties are welcome to attend!
A new primary energy source modeled on our sun - to realize this vision, plasmas with extreme temperatures of 150 million degrees Celsius must be confined. This is already possible today with the help of magnetic fields, and now fusion researchers are building the fusion experiment "ITER" (lat. the way), in which 500 MW of fusion power will be generated for the first time.
In this lecture, we will explain the physical principles of fusion in magnetically confined high-temperature plasmas and what challenges have to be overcome on the way to a fusion reactor - especially with regard to the wall materials, which have to withstand the highest stresses in the fusion reactor.

Prof. Dr.-Ing. Awakowicz "Plasma, the all-rounder"
PD Dr. Horst Fichtner could introduce in his lecture different plasmas of the solar system and for phenomena like "the solar fire", the hundred thousand degrees hot solar wind, to which interplanetary space probes and astronauts are exposed, detailed and vrständliche explanations supply. Also the energetic cosmic rays he conveyed with an ease in his execution.
He was able to explain why the understanding of these plasmas is important for fundamental physics as well as for the prediction of the so-called space weather and space climate.

100 Ruhr researchers study cosmic rays
They are constantly raining down on us from space: cosmic ray particles. Scientists from the Ruhr University Alliance are founding a center to study them.
Cosmic rays are the link between the research areas of the working groups that have joined forces in the Ruhr Astroparticle and Plasma Physics Center, or RAPP Center for short. Around 100 researchers will celebrate the opening of the facility in the Ruhr University Alliance on September 21, starting at 7 p.m. in the Bochum Planetarium. An inaugural conference will have been held at RUB on September 22 and 23.
Questions from dark matter to planet formation
At the RAPP Center, researchers ranging from students to professors will work at the intersection of astrophysics, plasma physics and particle physics. They will ask questions like: What is dark matter, anyway? Where does cosmic radiation come from? Why is there more matter than antimatter? Which interactions of elementary particles are relevant and how can they be studied? What is the role of magnetic fields in the universe? How does planet formation work?
Funding
The RAPP Center is funded by the Mercator Research Center Ruhr (Mercur) with about 330,000 euros.

Dr. Dominik Bomans "Plasmas in and around Galaxies"
Prof. Dr. Ralf-Peter Brinkmann demonstrates that theory does not have to be gray, as Mephistopheles claimed in Faust. The plasma researcher addresses the following questions: Why are plasmas hot and cold at the same time? What does this have to do with theory? And what is the ultimate practical use of all this?

Dr. Dominik Bomans "Plasmas in and around Galaxies".
In the lecture series "All Plasma" we went out into space again. Dr. Domink Bomans explained vividly how plasmas form in and around galaxies and what we can learn from this about the formation and development of our universe.

Judith Golda and Julian Held "Plasmas to touch"
As part of the lecture series "Everything Plasma", Judith Golda and Julian Held gave a lecture on the topic "Plasmas to touch".
While in the previous lecture the distance of the discussed plasmas (stars, interstellar medium) was very large, the two speakers showed where we have points of contact with plasmas in everyday life. The participants of the lecture could look at plasmas, touch them and learn more about the tehnical background.

Dr. Kerstin Weis "Plasmas around Stars"
The next lecture in the series All Plasma was given by Dr. Kerstin Weis on the topic "Plasmas around Stars".
The motivation for the topic was described as follows: When we look into the cloudless sky at night, the stars all appear to us as whitish points of light - yet they are very different. The celestial bodies differ in mass, surface temperature and color. The sun is also a star, and - like all other stars - it consists of hot plasma. Stars, however, not only emit light, but also steadily emit plasma: as stellar wind or solar wind. Under certain conditions, the stellar wind can become visible as a colorful nebula surrounding the star.

Dr. Simon Hübner "Plasmas in the Atmosphere".
Plasmas are natural phenomena that have always held a great fascination for people. Be it the dreaded lightning, mysterious auroras or the warming sun, Dr. Simon Hübner presented many interesting backgrounds and details in his public lecture "Plasmas in the Armosphere". After the lecture there was a lively discussion and many questions were asked.

Imagefilm des SFB-TR 87
The SFB-TR87 is concerned with research into the synthesis of nanostructured functional layers using high-performance plasmas. The goal is to find a knowledge-based approach that covers the whole chain from energy supply to plasma properties to material and to understand the dependencies in detail. The SFB-TR87 has now released its first image film to give more insight into how it works. Dr. Christian Maszl was involved in writing the script and explains his contribution to the SFB in the video.

Start of the lecture series Alles Plasma with Dr. Christian Maszl "Plasma to go".
The new lecture series "Alles Plasma!" started at the event center "BlueSquare" of the Ruhr-Universität Bochum. Moderated by Jun.-Prof. Jan Benedikt, researchers from the Research Department Plasma present current research to the interested public.
Dr. Christian Maszl started the series with his lecture "Plasma to go". In a humorous way, the audience was taken on a tour through the world of plasmas. In passing, people learned where we encounter plasmas more or less hidden in everyday life.
