What is it about?
Radio frequency waves are often emitted by fusion grade tokamak plasmas. This work outlines a simple yet robust diagnostic that can passively detect these waves and provide key information on the wave properties. Two real life examples are shown.

Why is it important?
These waves are emitted from core plasma regions, locations that produce the most intense fusion reactions. This region is generally hotter than the Sun and can be challenging for other diagnostic methods. The detection method is simple, robust, passive, and simple to interpret.
Perspectives
This work paves the way for diagnosing core plasma regions in burning fusion plasmas in a passive, robust, and inexpensive method.
