FRC (Field-Reversed Configuration)

A Field-Reversed Configuration (FRC) is a type of plasma device used in fusion research. It involves creating a doughnut-shaped plasma where magnetic fields are arranged to contain and stabilize the hot, ionized gas without needing complex magnetic coils around the entire device. The plasma’s magnetic field is reversed in direction inside the configuration, which helps maintain its stability and confinement. FRCs are attractive for fusion because they can potentially achieve high plasma performance with relatively simple magnetic setups, making them a promising approach to harnessing clean, limitless energy from nuclear fusion.
