Abstract: Gamma ray detection can provide unique insights into the physics of thermonuclear plasmas and their constituents. Moreover, it can help us prevent one of the most damaging events during a tokamak disruption: the formation of runaway electrons. In synthesis: gamma ray detection is a powerful tool for the development of sustainable energy sources through controlled nuclear fusion.

This brief presentation provides an overview of the various gamma-ray detection techniques and the valuable information they provide on plasma impurities, fast ions and runaway electrons. It discusses the range of operations and challenges associated with the different techniques. Additionally, it presents innovative advancements in the use of gamma-ray spectroscopy as a neutron-independent technique for measuring fusion power in deuterium-tritium tokamaks.

Bio: Andrea Dal Molin is a researcher at the Plasma Science and Technology Institute of Milan, Italy. He obtained his M.S. from the University of Milano-Bicocca in 2017 and completed his Ph.D. in physics in 2021. His expertise spans the design, assembly, measurement, and data analysis of numerous gamma ray diagnostics utilized at the tokamaks ASDEX Upgrade, DIII-D, and JET. He served as a diagnostic specialist for gamma ray and neutron diagnostics during the second deuterium-tritium experimental campaign at JET. Presently, he continues his research on gamma ray and neutron spectroscopy for thermonuclear plasmas at the Plasma Science and Technology Institute of Milan.
