Characterization on the melting failure of CuCrZr cooling tube of W/Cu monoblocks during plasma operations in EAST
The behavior of ITER-like W/Cu plasma facing components under complex conditions in current tokamaks is one of the main concerns for ITER.EAST has installed a full upper W divertor with the ITER-like W/Cu monoblocks as targets since 2014.A melting failure of CuCrZr cooling tube of W/Cu monoblocks has occurred during the plasma campaigns in 2019.Due
