Prospects for control of ELMO rings

A conceptual approach to controlling some important properties of hot-electron plasmas created by electron cyclotron heating, particularly the high-beta ELMO Rings is described. The approach to be considered is based on the anticipation that a significant number of collisionless, warm electrons can be accumulated in limit cycles arising from one of several possible coherent interactions with the ECH fields. If stochastic behavior is restored to these electrons, they can be heated to the relativistic energies characteristic of ELMO Rings. The number of warm electrons that can be manipulated for control purposes can also be affected by choice of system parameters
