用JT-60 U装置上的38通道光纤阵列同时测量了偏滤器区D Ⅰ和C Ⅱ-Ⅳ的绝对谱线强度的空间分布。偏滤器区的辐射损失已从强度导出。在没有MARFE的L模式放电中，由于氘和碳的辐射损失的分数分别为36%和64%。在物理溅射的假设下，基于碳离子的约束时间，通过一个简单的杂质模型将碳辐射与碳流入量联系起来。由于碳辐射的功率占MARFE辐射损失的大幅度增加。
Spatial distributions of absolute line intensities of D I and C II-IV in the divertor region have been measured simultaneously with a 38-channel optical fibre array in JT-60U. The radiative losses in the divertor region have been derived from the intensities. In L-mode discharges without the MARFE, the fractions of the radiative losses due to deuterium and carbon are 36% and 64%, respectively. The carbon radiation is related to the carbon influx by a simple impurity model based on the confinement time of the carbon ion on the assumption of the physical sputtering. The power radiated due to carbon accounts for a large increase in the radiative losses by the MARFE.
