Workshop
Understanding the theory of particles in plasmas
On Monday, January 22nd, scientists meet at RUB for the yearly meeting "Plasma and Particle Theory Day" to discuss the theory of particles in plasmas. Understanding the collective behavior of ionized particles is in the focus of research. A particular challenge is to understand how physical collisions of particles and the interactions between ions and electromagnetic fields are included in the various equations to describe the systems. In astrophysics, often these equations are dominated by the interaction of particles with electromagnetic waves. This is the research focus of the Collaborative Research Center SFB1491, "Cosmic Interacting Matters - From Source to Signal", centered at RUB. The research department of Plasmas with Complex Interactions also hosts SFB1316, "Transient Atmospheric Plasmas: From Plasmas to Liquids to Solids". Here, non equilibrium processes in atmopsheric plasmas for species conversion are the topic of research. Compared to astrophysical plasmas, these atmopsheric plasmas are very dense and physical collisions dominate the equations. It is the goal of the Plasma and Particle Theory day to move toward exploring the region in which both terms play a significant role. This is for instance the case in molecular clouds in the Milky way, in which the degree of ionization is as low as ~30% and naturally, collisions become important in the description. Another example is the physics of lightning that can be tested in the plasma lab and for which a briding theory is needed to understand the physics of atmospheric lightning. Once the particle interactions become inelastic, i.e at high energies or at extreme densities like they exist in neutron stars, the classical description needs to be replaced by the quantum mechanical one. Scientists therefore discuss the different methods, how synergies can be build and what the next steps are to build a consistent framework to combine classical and quantum-mechanical interactions.

Outreach
Plasma Physics for high school students
The project week for high school students is an educational program of the CRC 1316, the Faculty of Physics and Astronomy at the RUB and of zdi (Zukunft durch Innovation; Future through innovation). Which takes place twice a year.
From April 3-6 , the project week was hosted for 60 female students in grades 8 to 10. The girls chose be- between four workshops: plasma physics, astronomy, physics in medicine and sustainable house design. The project “From Plasma to Gold Layers” allows the students to gain an insight into the generation and applications of plasmas. Using the sputter coater and professional laboratory equipment, the students could deposit and examine gold layers themselves. During the project week, the students attended a lecture by Prof. Dr Judith Golda on “hands-on plas- mas – between material science and medicine“, and visited laboratories and the Planetarium Bochum. On the closing day, the results of the students’ research were presented in a poster session, followed by a quiz and lunch. The next project week in Autumn for female and male students in grades 8 and 9 will take place from October 9-13 .
The Faculty of Physics enables students to complete a school internship in Physics. From March 27-31, we welcomed two interns from grade 9. After a short introduction to plasma physics, the students worked on the sputter coater. They examined the coated samples. For this purpose, they determined the transmission with a spectrometer, the layer thickness with the profilometer and the conductivity. The interns also gained experience in handling data and in data evaluation. The goal of the internship is also to give an impression of laboratory work and current research. Therefore, doctoral students, bachelor’s and master’s students guided the interns through the labs and presented their experiments. The interns also visited the NRW state competition “Jugend forscht”, which took place at the Ruhr University Bochum March 27-29 .
The “mobile plasma workshop” took place for the first time on June 5, and visited an 11th-grade physics class in Essen. In the beginning, the students watched a short movie and received basic knowledge about plasmas and their applications. After a short quiz, they worked on the experiments in smaller groups. The students examined the light emitted by plasmas with an optical spectrometer and observed how electric and magnetic fields can influence plasmas. Information on the experiments on the students' tablets guided the workshop. The workshop was a success, and the students showed great interest. Through the students’ feedback, we have gained insights on how to improve our workshop going forward.
DAAD Exchange
Scientific results of DAAD exchange presented at ISPC 25
Prof. Judith Golda from RUB and Prof. Claire Douat from GREMI in Orléans have arranged several exchange visits between the groups with measurement cam- paigns in the respective laboratories within the frame- work of a DAAD exchange program (part of a PROCOPE project) and have already partially carried them out. The focus of the exchange is on the investigation of the role of CO in the treatment of biological substrates.
At the end of April, the French delegation consisting of Prof. Claire Douat, Eloise Mestre and Dr. Inna Orel was again in Bochum to measure rotational temperatures on the kHz-jet from Orléans. Here, with the support of Dr. Laura Chauvet as well as Daniel Henze in the labora- tory of Prof. Judith Golda, experimental results could again be obtained. In the end, several successful meas- urement campaigns were carried out over the last few visits. Therefore, the revisit was used to lay the foundation for a cooperative publication of the two groups, which will be submitted soon. Finally, Eloïse Mestre presented their results at the ISPC 25 conference in Kyoto, Japan.
