Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

An FM reflectometer is developed to measure the density profile of the MP2 device. It operates in the frequency range of 7.78-12.38 GHz. Phase information is obtained by digitizing the IQ detector outputs. However, the measured signal is significantly contaminated by noise due to microwave reflection at various points because the emitting and receiving antennas are installed outside of the vacuum window. A center aligned Fourier transform is used to remove the noise and extract the correct phase information from the measurement. In this paper, data analysis techniques are introducedplasma density profile is shown.
