FEATURE ARTICLE
" This record-breaking magnet is the culmination of the last three
years of work and will give the world a clear path to fusion power
for the first time, " said Mumgaard. " The world needs a fundamentally
new technology that will support efforts to decarbonize on a
timeline that can mitigate climate change. This test of our magnet
proves we have that technology, and we're on our way to producing
clean, limitless energy for the entire world. "
New commercially available high temperature superconducting
tape was used to build the magnets that will enable significantly
stronger magnetic fields. While existing tokamaks rely on device
scale to attempt net energy, HTS magnets enable a high-field approach
that will enable CFS to reach net energy from fusion with
a device that is substantially smaller, lower cost, and on a faster
timeline. " This groundbreaking magnet opens a widely identified
transformational and accelerated opportunity for advancing fusion
science and commercial fusion energy, " said Whyte, who is also a
co-founder of CFS.
Tokamaks are donut-shaped devices
that use magnets to control
and insulate a plasma in which
fusion occurs. While no fusion device
has yet to achieve net energy
from fusion, tokamaks have come
the closest with more than 160 tokamaks
built and successfully operated
around the world. The new
HTS magnets can enable significantly
stronger magnetic fields and as a result significantly smaller
tokamaks.

Superconducting magnets are key
Fusion, the process that powers the sun and stars, involves light
elements, such as hydrogen, smashing together to form heavier
elements such as helium and releasing prodigious amounts of energy
in the process. This process produces net energy only at extreme
temperatures of hundreds of millions of degrees Celsius, too
hot for any solid material to withstand. To get around that, fusion
researchers use magnetic fields to hold in place the hot plasma
which can be likened to a gaseous soup of subatomic particles,
keeping it from contacting any part of the donut-shaped chamber.
The magnet is composed of 16 plates stacked together, each one of
which by itself would be the most powerful high-temperature superconducting
magnet in the world.
