H-alpha Diagnostics

H-alpha diagnostics refers to a method used in plasma physics to analyze the properties of ionized gases, or plasmas, by studying a specific wavelength of light, known as the H-alpha line. This light is emitted when hydrogen atoms in the plasma transition between energy levels. By measuring the intensity, width, and shape of the H-alpha emission, scientists can gather information about the plasma's temperature, density, and flow dynamics. This helps researchers understand phenomena in various fields, such as astrophysics and fusion energy, where controlling and studying plasma behavior is crucial.
