Fusion products

camera neutronica di FTU FTU neutron camera

Measurement of the fusion products from the deuterium-deuterium (DD) or deuterium-tritium (DT) reactions is fundamental to thermonuclear fusion experiments based on magnetic confinement (tokamak).
The number of neutrons emitted during a tokamak plasma shot allow us to determine the fusion power, in other words, the energy produced through the fusion reaction. Neutron spectroscopy measurements also provide information on the temperature reached and the energy distribution of the interacting ions.

The laboratory participates in the Frascati Tokamak Upgrade (FTU) and Joint European Torus (JET) experimental campaigns, using its own instrumentation (the figure shows the neutron camera operating at FTU).

The laboratory is also involved in the study of runaway electrons, i.e., accelerated electrons inside the vacuum vessel, which interfere with the normal operation of a tokamak and which can cause serious damage to the structure, especially during disruptions (events that lead to a sudden loss of the plasma).

Other laboratory activities are the development of neutron and gamma detection systems (also based on recent digital acquisition techniques) and the design of diagnostics of fusion products for the future fusion reactor ITER.
