Interpretation of divertor Langmuir probe measurements during the ELMs at JET

We present results of massively parallel kinetic simulations of the triple Langmuir probes at JET. These results indicate that the probes under certain conditions, e.g. during ELMs, can significantly under/over estimate the electron temperature.
