Magnetized target fusion

Definition

Magnetized target fusion is a type of nuclear fusion that combines aspects of inertial confinement and magnetic confinement. In this approach, a plasma is created and contained using magnetic fields while being compressed by an inertial shock wave generated from an outer shell. This method aims to achieve the conditions necessary for fusion reactions in a more efficient manner, potentially leading to cleaner and more sustainable energy sources.
