stellarator

A stellarator is a type of device used to confine hot plasma in the field of nuclear fusion research. Unlike tokamaks, which rely on a doughnut-shaped magnetic configuration and induced plasma current, stellarators use helical magnetic fields generated by external coils to confine the plasma without the need for a current. This configuration aims to maintain stability at high temperatures and pressures necessary for fusion reactions. Stellarators are considered advantageous because they can operate in a steady-state mode, potentially leading to more efficient energy production in future fusion reactors. The design of a stellarator is more complex due to the intricate arrangement of the magnetic coils, but it provides a promising avenue for achieving sustained nuclear fusion.
