Thomson Scattering

Thomson scattering is a process where light interacts with free electrons in a plasma—a state of matter where gases are ionized. When photons (light particles) hit these electrons, they scatter in different directions. By analyzing the scattered light, scientists can determine properties of the plasma, such as electron temperature and density. This diagnostic tool is essential for studying fusion reactors, space plasmas, and other ionized gases, providing insights into their behavior and dynamics. Ultimately, it helps us understand how plasmas function, which is crucial for advances in energy production and space exploration.
