High-Frequency Diagnostics

High-frequency diagnostics refer to techniques used to analyze plasma, the fourth state of matter found in stars and fusion devices, using electromagnetic waves at high frequencies. These diagnostics measure various properties of plasma, such as temperature, density, and stability, by observing how plasma interacts with these high-frequency waves. By assessing changes in the waves, scientists can gain insights into the behavior of the plasma, helping improve fusion technology and our understanding of cosmic phenomena. Essentially, it's a way to "listen" to the plasma and learn about its characteristics and dynamics.
