摘要：

A new infra red camera (IR) for high resolution infra red studies for the outer divertor target plate in JET has been installed. Shot integrated energy balance between tile embedded thermocouples and IR based estimation of deposited energy on the outer tile gives fair agreement in the range of 80-120%. The assumptions of the temporal evolution of type-I ELMs power load as made for ITER define a lower, conservative boundary within the observed variation of the data. The broadening of the ELM induced power profiles are, in contrast to earlier results based on a lower resolution IR system at JET, found to be in the range of 1.4-4.3 when compared to the inter-ELM wetted area.
