Neutron scattering is one way to find out.
The Spallation Neutron Source at Oak Ridge National Laboratory offers fusion researchers with the U.S. ITER Project Office at ORNL, the Japanese Atomic Energy Agency and the ITER Organization a unique resource for improving the performance of superconducting cables.
In the ITER design, toroidal magnetic confinement fusion relies on superconducting cable that must endure extreme magnetic fields and electromagnetic forces.
SNS has the most intense neutron beams of any pulsed neutron source in the world, and the facility’s VULCAN engineering diffractometer can handle large samples like the ITER cable.
“VULCAN provides unique information on actual volume fractions and residual strains in constituent materials that is very valuable for characterizing the true state of superconducting cables,” said Wayne Reiersen of the U.S. ITER Project Office.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
