This thesis considers the role of large orbits of high energy minority ions during ion cyclotron resonance heating (ICRH) on a two-component plasma in JET. The model includes guiding centre orbits in the calculation of the minority ion distribution function and of the radial profiles of the collisional power with electrons and background ions. The results differ substantially from previous models in the estimate of the number of high energy particles and in the electron power deposition profile, which deviates considerably from the usual Gaussian shape. This orbit model is then applied to the calculation of the fusion yield in ICRF heated (3He)D plasmas, heat transport and interactions of 3He ions with plasma impurities during ICRF heating.
