Measuring and modelling polarized synchrotron emission from runaway electrons in fusion experiments

Research Project, 2020 – 2021

One of the high-priority areas for the success of fusion devices is the understanding of runaway electron dynamics. In this project we will use the Chalmers-developed SOFT tool (for Synchrotron-detecting Orbit Following Toolkit) to simulate polarized synchrotron emission emitted by runaway electrons, measured by the Motional Stark Effect (MSE) diagnostic at the JET experimental facility, UK. The radial profile of the total MSE signal (intensity) can complement camera images to determine the runaway density profile, which is important for validation of theoretical models. A good understanding and modelling capacity of runaway electrons will aid in finding ways of controlling them.
