Abstract

The ion to electron temperature ratio (T//i/T//e) is a crucial parameter that affects fusion plasma performance, especially for higher temperature advanced fuel operation. An important factor in the determination of T//i/T//e is the equilibration of energy between ions and electrons. The effect of changes on equilibration rates due to the presence of a magnetic field are considered here. It is found that rates are increased for low beta ( similar 10%) high temperatures ( similar 75 kev) Cat-D plasmas, causing a decrease in T//i/T//e and a corresponding increase in n tau //E for ignition of similar 75%. This effect is less pronounced for high-beta plasmas. Scaling of the changes in equilibration power with macroscopic quantities are presented.
