Summary
By proper tayloring of the plasma current profile it is possible to obtain tokamak equilibria which remain wall stabilized up to substantially greater values of the critical β than has previously been reported. Such equilibria, if attainable, possess an adequate safety factorq, and might represent a very attractive reactor operating regime.
Riassunto
Con un adattamento opportuno del profilo della corrente del plasma è possibile ottenere equilibri del tokamak che rimangono stabilizzati rispetto alla parete fino a valori del β critico sostanzialmente più alti di quelli precedentemente stabiliti. Tali equilibri, se ottenibili, possiedono un adeguato fattore di sicurezzaq, e potrebbero rappresentare un regime operativo del reattore molto attraente.
Резюме
Отмечается возможность получения равновесия в Токамаке, при котором стабилизированная стенка сохраняется вплоть до значений β, которые значительно больше критической величины β, чем сообщалось ранее. Такое равновесие, если оно достижимо, обладает адекватным фактором безопасности,q, и может представлять очень заманчивый рабочий режим реактора.
