This paper shows how ion cyclotron emission (ICE) provides a unique diagnostic tool for fusion alpha particles. It reviews the experimental method used during the preliminary tritium experiment in JET, and presents the experimental results. These indicate that fusion alpha particles, rather than beam ions, provide the free energy for generating ICE. The close relationship between the neutron flux and the ICE is well modelled by the TRANSP code. The results are discussed in the context of collective emission models in which cyclotron harmonic radiation is excited by a diffuse, high energy ion population.
