Upgraded acceptance criteria from transient thermography control for the W7-X divertor target elements

Pre-series and testing route for the serial fabrication of W7-X target elements

“…The method is based on the detection of the delay in the surface temperature evolution introduced by an abrupt change of the temperature of the water flowing in the cooling channel, which has been recently completed by advanced post data processing techniques [14]. The results of the analysis also showed a homogeneous quality of the tiles including the repaired ones, and that no defects are expected to occur during the following HHF testing.…”
