A stellarator is a type of fusion reactor that uses a complex arrangement of 3D magnetic coils to confine plasma in a steady state without the disruptions seen in tokamaks.
Stellarators aim to overcome the limitation of tokamaks by providing a steady-state confinement without the disruptions that can cause energy loss and limit operational time.
By employing a twisted magnetic configuration, stellarators generate a stable and continuous magnetic field that confines plasma. This design avoids the need for active stabilization systems used in tokamaks, making it potentially more reliable but also harder to build and maintain.
The manufacturing process for stellarators is highly complex due to the intricate design requirements. It involves precise engineering and assembly of multiple magnetic coils, which must be perfectly aligned to achieve the desired magnetic field configuration.
Construction begins with detailed simulations and modeling to ensure the magnetic fields are correctly configured. The magnetic coils are then precisely manufactured and installed in a toroidal geometry to create the confinement field. Testing involves extensive validation of plasma behavior under various conditions.
