Heating and Current Drive by Waves

This lecture covers the use of waves for heating and driving current in tokamaks, focusing on Ion Cyclotron Resonance Heating (ICRH) and Lower Hybrid (LH) waves. It explains the basic mechanisms, antenna features, and additional plasma heating methods. The lecture delves into wave-particle resonances, ion and electron cyclotron resonance frequencies, and the absorption schemes for ICRH. It also discusses the ICRH system for ITER, modeling of ICRH, and the pros and cons of ICRH heating and current drive. Furthermore, it explores the use of LH waves for heating and current drive, including the antenna design, current drive efficiency, and the LH system for ITER.
