Proxima Fusion, @plasmaphysik, and the state of Bavaria have signed an agreement to build a new fusion reactor in Germany — a meaningful step forward for European fusion energy.

The Alpha device is based on a stellarator concept, building on the physics foundation of Wendelstein 7-X. The goal is to reach Q > 1 (net energy gain) and to advance the path toward a stellarator-based fusion power plant built in Europe. #Fusion

@plasmaphysik After #Wendelstein7X delivered in each of its experimental campaigns impressive results, fusion community could not longer ignore stellarator as a very attractive concept of fusion power plant. It resulted in a bunch of startups who claimed they want to build stellarator reactor. Proxima Alpha with backing of @plasmaphysik - world leading institution in fusion science - is one of the most promising project at the moment

The main difference between tokamaks - most advance reactors based on the concept of confining hot fusion plasma with a magnetic field - and stellarators is that the latter does not need plasma current to create it magnetic field and therefore is inherently stable. It’s a difference like between keeping a broom’s stick firmly in the hand (stellarator) and balancing it on a finger (tokamak). #Fusion #Wendelstein7X
