During recent years, ion cyclotron resonance heating (ICRH) has developed into a reliable heating method for large tokamak plasmas. Modelling of ICRH has also developed to include time dependent calculations and effects of real drift orbits, i.e. effects caused by the fact that a drift orbit does not coincide with a single flux surface. In this paper it is shown that the present theory is in good agreement with JET ICRH experiments. Comparisons between time dependent simulations and experiments in ion cyclotron heated plasmas in the JET tokamak have been undertaken. Heating was simulated with a time dependent code, PION-T. The scenario analysed was minority heating of hydrogen at the fundamental cyclotron resonance in a deuterium majority plasma.
