TL;DR: In this paper, the authors explored novel concepts for fusion chamber technology that can substantially improve the attractiveness of fusion energy systems, including the potential for: (1) high power density capability; (2) higher plasma β and stable physics regimes if liquid metals are used; (3) increased disruption survivability; (4) reduced volume of radioactive waste; (5) reduced radiation damage in structural materials; and (6) higher availability.

TL;DR: In this article, an inversion algorithm for three-dimensional profile reconstruction of wall thinning defect in a double-layer region of a typical coolant pipe of nuclear power plants from pulsed eddy current testing (PECT) signals has been proposed and experimentally validated, based on a fast simulator of PECT signals and a deterministic optimization strategy.

TL;DR: In this paper, a low frequency ECT method for carbon fiber reinforced polymer (CFRP) inspection was proposed. But, this method is more susceptible to various interference factors, causing many difficulties in the system construction and implementation.

TL;DR: In this article, the eddy current response signals from FCD 450-600 grades of cast iron were measured and a good correlation with their hardness and tensile properties was found.

TL;DR: A comparison of numerical results of the two proposed simulation methods and experimental results indicates that both of these simulation methods can model PECT signals with high precision, but the frequency domain summation method combined with an interpolation strategy is much more efficient in its use of simulation time.
