Summary
A modified Kirchhoff law is applied to the evaluation of the cyclotron emission from a toroidal plasma with a suprathermal electron component with Maxwellian distribution. The radiation temperature is obtained for the ordinary wave at the first cyclotron harmonic and for the extraordinary wave at the second cyclotron harmonic, both for transverse and oblique propagation with respect to the toroidal magnetic field.
Riassunto
Si analizza l'emissione alla frequenza ciclotronica elettronica di un plasma toroidale utilizzando una legge di Kirchhoff modificata che tenga conto della presenza di una componente elettronica sopratermica di tipo maxwelliano. Questo metodo permette di calcolare la temperatura di radiazione quando si conosca il solo coefficiente di assorbimento. Si effettua il calcolo esplicito della temperatura di radiazione per l'onda ordinaria, alla frequenza di ciclotrone, e per l'onda straordinaria, alla seconda armonica, per propagazione sia perpendicolare sia obliqua rispetto al campo magnetico esterno. I risultati possono essere facilmente applicati ad un'ampia classe di parametri di plasmi toroidali.
Резюме
Модифицированный закон Кирхгофа применяется для вычисления циклотронного излучения из тороидальной плазмы с надтепловой электронной компонентой с Максвелловским распределением. Определяется температура излучения для обыкновенной волны на первой циклотронной гармонике и для необыкновенной волны на второй циклотронной гармонике при распространении перпендикулярно и наклонно по отношению к тороидальному магнитному полю.
