Diagnostics: Plasma Properties and Measurements

This lecture covers the importance of accurate measurements in plasma physics, focusing on passive and active diagnostics. Topics include plasma properties such as density, flow velocity, and temperature, as well as the use of diagnostics like Langmuir probes, interferometry, and Thomson scattering. The lecture also delves into different types of measurements, such as radiation diagnostics, spectroscopy, and magnetic measurements, highlighting the significance of bremsstrahlung and line radiation. Various techniques for determining electron temperature, such as using filters and analyzing spectral line shapes, are discussed. Additionally, the lecture explores the role of magnetic fields in plasma diagnostics and the methods for measuring them.
