Feasibility of an ECRH system for JET: wave propagation,absorption and current drive
Investigation of electron cyclotron wave propagation, power absorption, and current drive has been performed for a set of JET scenarios, aiming to assess the optimal wave frequency, launching position, and injection angles to achieve the various physics goals of an EC system in JET. EC power absorption and current drive have been computed for three values of the EC frequency, namely, 113 GHz, 150 GHz, and 170 GHz. On the basis of extensive beam tracing calculations performed in a wide range of magnetic fields (2.5 T ?3.4 T), the frequency of 170 GHz has been chosen, since it covers the wider magnetic field range of operation in JET and corresponds to that foreseen in ITER.
