The TFTR tokamak is used to evaluate discharge evolution and control, when these are broken down into discharge, initiation, volt-second consumption, and current and density ramp-up and ramp-down. Control of the current ramp-up using a plasma growing technique will be described, and the advantages of this method compared to using constant major and minor radii will be discussed. The control of density using gas puffing, pellet injection, and neutral beam fueling will be presented, along with a discussion of the density range which is found to increase with plasma current. 23 refs., 11 figs., 2 tabs.
