Summary
The condition for fusion breakeven is derived for the hot-ion mode in which the ion temperature considerably exceeds the electron temperature. It is found that the conditions for breakeven in this mode are greatly eased compared to the case of equal ion and electron temperatures. The critical value of the electron temperature is strongly reduced indicating the possibility of reaching breakeven with relatively weak additional heating.
Riassunto
Si ricavano le condizioni per il pareggio energetico della fusione termonucleare nelhot-ion mode dove la temperatura ionica supera apprezzabilmente quella elettronica. Si trova che le condizioni di pareggio in questo modo sono assai meno restrittive che per il caso di temperature ioniche ed elettroniche uguali. Il valore critico della temperatura elettronica è fortemente ridotto indicando la possibilità di raggiungere il pareggio anche con riscaldamento ausiliario relativamente debole.
qRезюме
Выводится условие для «breakeven« при синтезе для горячей ионной моды, где ионная температура значительно превышает электронную температуру. Получено, что условия для “breakeven” в этой моде легко сравни-ваются со случаем равных температур ионов и электронов. Критическая величиа электронной температуры сильно уменьшается, указывая на возможность достижеиня “breakeven” с относительно слабым дополнительным нагреванием.
