VINETA is large enough to deliver relevant results, but small enough to carry out research in a timely manner. This is particularly attractive for Bachelor's and Master's theses. This makes it the ideal training machine, and it was used as such before Wendelstein 7-X was commissioned.  Some of those sitting in the Wendelstein 7-X control room today learned their trade at VINETA. When Wendelstein 7-X was commissioned in 2015, VINETA was no longer the focus at IPP in Greifswald. VINETA was offered to Prof. Manz as a kind of dowry for his appointment and will now serve as a training experiment at the university.

VINETA moved from IPP Greifswald to the university in spring 2022. We would like to thank Dr. Adrian von Stechow and Dr. Birger Buttenschön from the IPP. Unfortunately, the VINETA could not yet be put into operation due to a lack of electricity and water supply. In the end, it took until October 2024 to connect the power and water supply, after which Dr. Stefan Knauer, Dr. Nils Fahrenkamp and Sebastian Haag were able to get the experiment up and running again in no time at all - a truly impressive achievement. The working group took this as an opportunity to hold an inauguration ceremony for the newly constructed experiment to demonstrate the first official plasma. Similar to the launching of a ship, the experiment was given its new name - VINETA.75.   

Physicists from the University of Greifswald, IPP and INP scientists, young students and cooperation partners from the Universities of Stuttgart and Fukuoka were invited to the inauguration of the newly constructed VINETA.75 experiment. At the inauguration, IPP Director Thomas Klinger triggered the symbolic first plasma discharge - in front of some of the invited guests who were able to fit into the cramped laboratory. Prof. Klinger had designed the VINETA experiment during his first years as a professor together with a doctoral student at the University of Greifswald.

 

Guests from Japan

In February we had guests from Kyushu University in Fukuoka Japan. Donato Di Matteo and Chanho Moon took a look at the rebuilt VINETA.75 and helped with the first measurements. 

SepOS - from ASDEX Upgrade to SPARC

02/12/2025

In this recently published article, SepOS predictions are made for SPARC. The paper contains the previously unpublished SepOS databases for ASDEX upgrade for different magnetic field strengths and plasma currents. The minimum of the heating power limit of the L-H transition is analytically derived from SepOS. And the SepOS for SPARC parameters is presented.  

Review Paper on SepOS published

01/27/2025

An overview article about the SepOS was published. The SepOS concept has been pedagogically revised to make the concept more accessible. The work is more closely related to the Rogers, Drake and Zeiler (RDZ) model. This paper summarizes the recent developments regarding the turbulent control parameter and the SepOS. The outlook includes many new ideas.
