Plasma Diagnostics

Plasma Diagnostics refers to the collection of experimental techniques used to measure and characterize the properties of plasmas. Since plasmas are often hot, ionized, and difficult to access directly, diagnostics play a crucial role in understanding plasma behavior. Key plasma parameters include temperature, density, electric and magnetic fields, particle velocities, and radiation emission. Diagnostic methods can be intrusive, such as Langmuir probes, or non-intrusive, such as spectroscopy, interferometry, and Thomson scattering. Advanced diagnostics are essential in fusion research to monitor plasma confinement, stability, and transport. In space and astrophysical plasmas, remote sensing techniques are widely used. Accurate plasma diagnostics enable validation of theoretical models and simulations. They are indispensable for controlling plasma experiments and advancing applications in fusion energy, space physics, and industrial plasma technologies.
