Scientists from Germany have designed a revolutionary fusion energy device known as Wendelstein 7-X. The physicist of the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), Sam Lazerson decided to team up with a group of German scientists to work on the stellarator known as Wendelstein 7-X, located in Greifswald, Germany. This innovative device produces magnetic fields consistent with their intricate design.
On November 30, the new study was published in the Nature Communications magazine. The document unveiled an error field proving the deviation from the established layout of 1 part in 100,000. This outcome which was obtained could represent a significant critical step in testing the operability of stellarators. These devices could be used in the development of future fusion reactors.
PPPL is the leading US partner of Wendelstein 7-X. The fusion energy device designates the most complex and largest stellarator ever build. The Max Planck Institute for Plasma Physics in Greifswald was the company that worked on creating this new appliance. The development of the fusion energy device was finished in 2015. On the list of collaborators, there is DOE’s Oak Ridge team, Auburn University, Xanthos Technologies, the University of Wisconsin-Madison, the Massachusetts Institute of Technology and Los Alamos National Laboratories.
The purpose of stellarators is to restrict charged gas known as plasma which stimulates the fusion reactions happening in magnetic fields compared to symmetrical areas which create tokamaks if they are very widespread and used.
The twisty magnetic fields determine stellarators to manipulate the plasma without using the help of the current produced in the gas by tokamaks to complete the magnetic field. In this way, the plasma of stellarators will present a lower risk of disrupting which could determine the abrupt halt of the internal current and also fusion reactions will eventually shut down.
The most significant role in the development of the W7-X project was played by PPPL. It created and delivered massive trim coils responsible for tuning the magnetic fields of stellarators, allowing the determining of their measurements. Lazerson claimed that his team has confirmed that the magnetic field designed by them is working just as planned. He led approximately all the experiments prone to establish the configuration of the field.
He argues that all these were possible only with the support of the US contributions, underlining the ability of PPPL to conduct international partnerships.
