I am also currently involved with the HBT-EP experiment, doing experiments on resisitive wall mode feedback stabilization. HBT-EP is a tokamak (a toroidal shape that is not twisted) which is devoted to the study of magnetohydrodynamic instabilities and their feedback stabilization. This is of importance to fusion energy science since it will allow us to increase the pressure of the plasmas confined in tokamaks and therefore will help create a more economical fusion power plant.
