Electron cyclotron radiative transfer in the presence of polarization scrambling in wall reflections

F. Albajar, M. Bornatici, F. Engelmann2005年被引用 9Nuclear FusionIF 3出版社

An exact analytical solution of the equation of radiative transfer is obtained for a cylindrical system with specularly reflecting walls, accounting for the presence of polarization scrambling in the reflection process. The effects of polarization scrambling on the specific intensity of the radiation can be described, in part, via an effective wall reflection coefficient for the extraordinary (x) and ordinary (o) mode. For the special case of electron cyclotron radiation in a fusion plasma approaching reactor conditions, a numerical analysis of the impact of polarization scrambling on both the specific intensity of the radiation and the radial profile of the net power radiated as well as on the total power loss is carried out for ITER-like parameters in steady-state operation.

円筒系における鏡面反射壁を有する放射伝達方程式の厳密な解析解が、反射過程における偏光スクランブリングの存在を考慮して得られる。反射過程における偏光スクランブリングが放射の特異強度に及ぼす影響は、一部は異常波(x)モードおよび常波(o)モードに対する実効壁反射係数を介して記述することができる。炉条件に近づく核融合プラズマにおける電子サイクロトロン放射の特別な場合について、偏光スクランブリングが放射の特異強度および正味放射出力の動径分布、ならびに全出力損失に及ぼす影響の数値解析が、定常運転におけるITER類似パラメータに対して実施される。
