Abstract
New experimental results from disruption heat flux simulations in the millisecond range with laser and electron beams are discussed. For a number of graphites, boronated graphites and carbon fiber composites, the effective enthalpy of ablation is determined as 30±3 MJ/kg, using laser pulses of about 0.3 ms. No effect of boron doping on the ablation enthalpy is found. A simple parametric study of vapour shielding is presented, with shield transmission factors from 5 to 100% and compared with recently published results from pulsed plasma devices in Russia. Estimates for the disruption erosion lifetime of plasma facing components in ITER are briefly discussed.
