What is it about?
In science, photographs are often taken for granted. This is mostly because up to a couple of decades ago they were only considered qualitative. However, advanced microscopy and quantitative imaging techniques have contributed significantly to material science—in the same way photographs of celestial bodies have contributed enormously to astronomy. I've used many techniques of digital microscopy to explain a very relevant issue in superconductor cable-in-conduit conductors. For this article and its subsequent parts, the good the bad and the ugly of these conductors are revealed by microscopy.

Why is it important?
Cable-in-conduit conductors seem to be our best option for fusion applications. Thinking about the future fusion projects that will base their technology on the lessons learned by ITER, this paper (and its subsequent parts) will be of importance for the design of those magnets.
Perspectives
In the R&D side, ITER is old news... I expect this paper to remain low referenced until the next machine (DEMO) starts becoming a reality.
