聚变等离子体中杂质碳的辐射损失

RADIATIVE LOSS FOR CARBON PLASMA IMPURITY

用修正的日冕模型，考虑原子的亚稳定态结构，计算了聚变等离子体内杂质碳原子及其离子的辐射损失。结果表明，当等离子体内电子温度小于１００ｋｅＶ时，在等离子体装置的设计和运行中必须考虑杂质原子、离子的辐射功率损失。它对聚变等离子体系统的局部能量平衡和总能量损失的贡献是重要的。

The radiative loss for carbon plasma impurity by modified Corona model with metastable state effects is calculated. The result indicates that radiative power loss of plasma impurity such as carbon is necessarily taken to account under the electron temperature from 1 eV to 100 keV in design and operation of plasma device. It has significant contribution to the local power balance and the total energy loss in plasma fusion system.
