给出了由MAST红外摄像机计算的目标热负荷。参数（α）用于说明表面效应。在L模式放电中，到达靶的能量，如使用适当选择的α从相机计算的，与从朗缪尔探针计算的以及从核心损失的能量一致。在H模式下，能量平衡也可以在ELM和ELM间时段实现，尽管对于不同的目标和不同的功率负载需要不同的α值。这可能是由于增加的侵蚀导致在等离子体鞘中产生灰尘。
Target heat loads calculated from the infrared camera on MAST are presented. A parameter (α) is used to account for surface effects. In L-Mode discharges, the energy arriving at the targets, as calculated from the camera using a suitable choice of α, is in agreement with that calculated from Langmuir probes and that lost from the core. In H-Mode, energy balance can also be achieved both at the ELM and in inter-ELM periods, although a different value of α is required for different targets and for different power loads. This may be due to increased erosion leading to the production of dust in the plasma sheath.
