| Abstract: | Conclusion The zero-dimensional analysis and the numerical calculations have shown that stable conditions of the thermonuclear burning in a tokamak with a high plasma density are achieved only when  E depends strongly upon the plasma temperature (E –  m, where m<–2). Since in the experiments the retention laws have a significantly weaker temperature dependence, special measures are required for obtaining stable burning. Such conditions are reached by introducing feedbacks over, say, the plasma temperature and the rate of plasma-temperature change. It was shown in the present work that the corresponding regulation parameters are on the 0.3–0.5 level. Feedback can be obtained by, say, relaying operation of the source of additional heating.Translated from Atomnaya Énergiya, Vol. 63, No. 2, pp. 147–148, August, 1987. |
