Analysis of Textor disruption thermal data

Russo, A.J.; Watkins, J.G.; Finken, K.H.; Dippel, K.H.; Moyer, R.A.; Gray, D.

Infrared video thermograms of a portion of the surface of graphite limiters in Textor were taken during several disruptions. Estimates of the deposition power density were made by comparison of the observed temperature histories with those calculated from a numerical thermal conduction model. It was found that the heat flux, at the observed locations, often occurred in sharp submillisecond bursts, the magnitudes of which were much larger than the heat flux density averaged over the whole disruption. 5 refs., 4 figs.
