CHARGED FUSION PARTICLES IN A TOKAMAK
"Fusion rates" have been generally reduced to "neutron flux" for 25 years. Other particles are generated (protons, tritium, helium-3 and 4); but, charged, they are more or less confined in the magnetic fields. Results reachable by charged fusion products analysis justify the work, especially on the large experiments like Tore-Supra or J.E.T., where the power produced may reach a few MW. They can be used as diagnostic for the plasma, and as experimental prediction of the confinement of alpha particles, which is necessary for the reactor. Practical use of a semi-conductor detector on a Tokamak is technically different : the problems have been studied on T.F.R.. Encouraging results have been obtained, with 3 MeV (D-D) and 15 MeV (D-He**3) proton spectra.
