Description
Recent results from the DTE2 and DTE3 deuterium-tritium (DT) campaigns at the Joint European Torus demonstrated the feasibility of an alternative approach to measuring fusion yield, based on the absolute detection of DT fusion gamma rays emitted by the secondary branch of the DT reaction. Unlike conventional neutron-based fusion power diagnostics, this neutron-independent method does not require in-vessel calibration campaigns. Moreover, it can also be a convenient method for future aneutronic fusion fuels. This novel technique could provide neutron-independent validation of the fusion power achieved in scientific fusion experiments. At last, by improving the accuracy of fusion power measurements, this technique supports the safe and cost-effective operation of future fusion power plants, helping them to operate closer to their licensed performance limits.
