Foto de stock - 13 December 2022, Mecklenburg-Western Pomerania, Greifswald: Thomas Klinger, director at the Max Planck Institute for Plasma Physics, stands at a monitor in the control room of the Wendelstein 7-X fusion experiment. The monitor shows an image of a hydrogen plasma. After the extensive reconstruction, the experimental campaign at Wendelstein 7-X is running at full speed. Currently, scientists are generating and studying hydrogen plasmas. For this purpose, a measuring system is used that can accommodate various probe heads. These are immersed in the plasma edge in order to obtain information about the temperature of the plasma particles or the plasma density, for example, or to introduce gases or impurities into the plasma in a targeted manner.
