The Power of Synthetic Data Generation

Diag2Diag, developed by researchers from Princeton University, the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), and several other institutions, functions as a virtual sensor within fusion reactors. The AI analyzes data from existing sensors to generate synthetic data for other sensors that may be failing or too slow to capture critical events 1

Enhancing Plasma Control and Stability

One of the key advantages of Diag2Diag is its ability to provide more detailed information than actual sensors, particularly in critical areas such as the plasma edge, also known as the pedestal. This enhanced monitoring capability allows scientists to better control plasma stability and optimize fusion reaction efficiency 1
