<p>"At the end of a cold, concrete tunnel lies a massive, warehouse-like space, a labyrinth of cables, wires and copper pipes that lead to a circular vessel cradled by red magnetic coils.</p>
<p>Inside, the vessel is lined with black carbon tiles that can endure heat from a substance that crosses the million-degree Celsius mark.</p>
<p>The device the vessel, the cables, the huge box that powers a high-energy beam is the National Spherical Torus Experiment (NSTX), a nuclear fusion reactor at Princeton Plasma Physics Laboratory thats about to get a little more advanced. . . . (continued)</p>
<hr>
<p>Tremendous progress has been made in fusion research in the last twenty years and Princeton has been at the heart of those advances. The new NSTX reactor will take the U.S. and the world, one step closer to commercially-viable and environmentally clean fusion power.</p>
