New Separations Technology for Rare
Earths Focus of DOE Research Fundings

7-Tesla magnet system from Cryomagnetics
High-level scientific research goes on despite Covid-19
setbacks, as evidenced by deliveries from Cryomagnetics of
several of its cryogen-free systems to labs around the world. A
developer of superconducting magnet systems and cryogenic
equipment for scientific research, the company reports that it
has made several deliveries of its cryogen-free systems to labs
across the world recently.
Among them are the company's
9-2-2 Tesla C-Mag 3-Axis Superconducting Magnet System, shown
at right, that was delivered in July to
a facility in China. The cryogen-free
superconducting magnet system is
cooled by a single Sumitomo 1.5W
pulse tube cryocooler to conductively
cool the magnet and cryostat as well
as cooling a secondary closed loop
helium circuit used for controlling the
sample temperature. Up to 9 Tesla
is possible from it in the Z-Axis or
2 Tesla in spherical vector rotation,
says Cryomagnetics.
Another delivery in July brought its 7-Tesla Optical C-Mag Superconducting Magnet System to a lab in California. It is also a
cryogen-free system, this one utilizing a Sumitomo 1.0W pulse
tube cryocooler to conductively cool the magnet and cryostat
as well as cooling a secondary closed loop helium circuit used
for controlling the sample temperature. There is optical access
both axial and perpendicular to the magnetic axis feature via
diamond windows for measurement over a wide spectral range.
A bottom mounted window allows for access to the Z-axis.

Developing new technology for separations of rare earth materials are a focus of new projects funded by the U.S. Department
of Energy for several scientific research programs. Finding
alternative materials was also an objective in $20 million of
commitments going to five national laboratories for basic
research efforts aimed at ensuring a stable domestic supply of
rare earth elements which are deemed critical for a wide range
of technologies essential to the nation's energy, economic and
national security.
" Rare earth elements play an indispensable role in materials
needed for today's advanced technologies and are essential to
a functioning American economy, " said Dr. Chris Fall, director
of DOE's Office of Science, when the projects were announced
in April. " This fundamental research is aimed at both improving
current availability and supply of these elements and finding
promising alternative materials. " Nearly $7 million was pledged
for the initial year of the three-year programs.
The research will focus on improving the efficiency of both the
use of the elements and their extraction from geological and
recycled sources. It will also seek to reduce the reliance on rare
earth elements by discovering substitute materials with similar
or even enhanced properties. Four of the five programs focus
on advancing the science of minerals separations technology
as an enabler of processing rare earths.
Teams will include researchers from both DOE laboratories and
universities. The laboratories are Argonne National Laboratory,
Lawrence Berkeley National Laboratory, Los Alamos National
Laboratory, Oak Ridge National Laboratory and National Renewable Energy Laboratory.
