Description
The TU Dresden Neutron Generator (TUD-NG) is an accelerator-driven deuterium–tritium (DT) neutron source designed for fusion-relevant irradiation experiments. The facility delivers deuterium beams of several milliampere onto a water-cooled tritium target, producing neutrons via the 3H(d,n)4He reaction with energies around 14 MeV. The source is designed to reach neutron yields of up to 1012 n/s with nearly isotropic emission, making it the most intense DT neutron sources in Europe.
Originally commissioned in 2003, the facility has been used intermittently for applications in fusion research, astroparticle physics, and nuclear astrophysics. Current efforts aim to significantly expand its operation and transform the TUD-NG into a dedicated user facility for German and European fusion research.
The experimental infrastructure enables irradiation studies of materials and components under fusion-relevant neutron spectra, activation measurements for the validation of nuclear data and transport simulations, and investigations of key processes such as tritium breeding. By providing flexible and comparatively rapid access to 14 MeV neutrons, the TUD-NG is positioned to bridge the gap between small laboratory sources and future large-scale facilities.
In this contribution, the design and performance characteristics of TUD-NG are presented, together with plans and ongoing developments toward user operations.
