The DT neutron generator in Dresden: Fusion reactor studies, neutron activation analyses and nuclear astrophysics — •Steffen Turkat¹, Toralf Döring², Axel Klix³, Björn Lehnert¹, Max Osswald¹, Frederik Uhlemann¹, and Kai Zuber¹ — ¹Institut für Kern- und Teilchenphysik, TU Dresden — ²Helmholtz-Zentrum Dresden-Rossendorf — ³Institut für Neutronenphysik und Reaktortechnik, Karlsruher Institut für Technologie

The Deuterium-Tritium neutron generator of TU Dresden delivers proton and deuteron beams of several milliamperes with energies of up to 350 keV. So far, its primary application was focused on the generation of 14 MeV neutrons via the ³H(d,n)⁴He reaction, achieving rates of up to 10¹² neutrons per second. It is therefore Europe’s most intense facility of its kind, dedicated mainly to fusion reactor research and neutron activation analyses.

In addition, the laboratory’s scope extends to an even broader range of activities, including cross-section measurements, implantation studies, nuclear astrophysics, neutrino physics and others. This contribution will focus on the facility’s relevance for fusion reactor studies, but also trace its past, present, and future, as it transitions into a multi-purpose laboratory.
