Over the last thirty years, there have been increasingly ambitioustheories and experiments along the theme of exercising increasedcontrol over plasma by means of RF waves. The diversionof energy from energetic alpha particles to waves (alpha channelling) is such an attempt atdetailed control over plasma behavior. The effectcould accelerate progress towards an economicaldeuterium-tritium tokamak reactor. Recent simulations and experimentson TFTR support certain separate building blocks that taken togethermight produce the desiredeffect.
