Abstract :
A methodology for measuring instantaneous thermal loads on a portion of the Frascati Tokamak Upgrade (FTU) poloidal limiter was developed; such a methodology is based upon the processing of experimental data recorded by thermocouples and an infra red detector. By a proper calibration procedure, the instantaneous surface temperature of a portion of the limiter can be obtained; the deconvolution of the time-resolved limiter surface temperature provides time-resolved thermal loads. In this paper the apparatus is described and some examples of elaborated data are given
