内容記述 | "Ignition characteristics in D-T helical reactors of various sizes are studied with the operation path method on the bar{P}_ht tau_E^2-T plane and the POPCON method. Based on the empirical LHD scaling, a confinement has to be improved by more than a factor of 1.5 for reaching ignition and more than a factor gamma_H =2 to have optimum fusion power in a reference helical reactor with R > 8m, bar{a}=2 m, and B_o > 6 T. The density limit and the confinement time saturation effect with respect to the density degrade the favorable density scaling of the confinement time (tauE proportional to n^0.69 and are found to be important limiting factors for ignition characteristics. For a reactor of R = 10 m, bar{a}=2 m, gamma_H=2, B_o=7T with an external heating power P_ex=100 MW, the minimum auxiliary heating power is around 55 MW at an operating density 40% below the density limit, and ignition can be reached in a finite time. The ignition characteristics for larger size (R=15 and 20 m) reactors and gyro-reduced Bohm scaling are also studies." | |||||
