Magnetic confinement devices, such as tokamaks and stellarators, use powerful magnetic fields to suspend the plasma away from physical walls while heating it to extreme temperatures. At this nuclear fusion temperature , the gas becomes plasma, and the nuclei have a sufficient probability of fusing when they collide.
Plasma Confinement at Nuclear Fusion Temperature
Methods of Achieving Fusion Conditions Different experimental approaches tackle the challenge of reaching the required temperature using distinct methods. The allure of fusion lies in its potential to provide a nearly limitless source of energy using abundant fuel sources like deuterium from seawater, with helium as a benign byproduct, all without the long-lived radioactive waste associated with fission.
Overcoming the Coulomb Barrier The primary challenge in achieving fusion is overcoming the Coulomb barrier, the electrostatic repulsion between nuclei. Confinement Time It is crucial to understand that temperature exists alongside another key factor: confinement time.
Plasma Confinement at Nuclear Fusion Temperature
Techniques such as Thomson scattering, where lasers are fired at the plasma and the scattering of light reveals particle speeds, provide accurate temperature readings. Because nuclei repel each other electrostatically, they must be moving at extraordinary speeds to bridge the gap.
