RESEARCH & DEVELOPMENT

Low Field Modular Room Installed at University Labs
Magnetic Shield Corporation has recently completed large-scale,
shielding installations at two research universities. One was at
the University of Illinois Champaign-Urbana Electron Microscopy
facility in its Materials Research Lab (MRL), while the other was
at Virginia Polytechnic Institute in its Carilion School of Medicine
and Research (VTCRI), located in Roanoke, VA.
Both installations involved equipping the research labs with the
company's specially customized modular MuROOM constructed
with several layers of its proprietary high permeability MuMETAL
electromagnetic shielding alloy sheet material for reduction of
low-frequency DC and AC fields to the nano-Tesla range.

MuROOM at University of Illinois

The project at the University of Illinois, whose Materials Research Lab is considered one of the world's leading materials research centers, was constructed in segments during 2017-2018
to house a scanning transmission electron microscope used for
scientific research. The new shielding room was built to meet the
demanding specifications of the ultrasensitive microscope, using Magnetic Shield's
Perfection-AA annealed sheet which is
designed specifically to meet low-field
specifications. The sheet panels provide
low frequency electromagnetic interference
shielding in the range of 0-300 Hz.
"Our high nickel-iron alloy MuMETAL sheet
is processed through our specialized, perfection annealed heat treatment process
which produces the optimum shielding

"MuROOMS are designed to shield critical lab applications at
low field frequencies, but quasi-DC, broader or higher RF ranges
may employ other materials such as copper. Ultra-sensitive hightech instrumentation applications such as scanning, and electron
microscopy require a high degree of precise accuracy and timeinterval performance throughout experimentation. MuROOMs
accomplish these challenging requirements. Our team builds the
room on location at the client's designated area or facility."
MRL is an extensive laboratory. It has one of the largest sharedinstrumentation facilities in the nation, with over 100 advanced
instruments for materials fabrication, processing and characterization, supporting the education and research of over 1,000
scientists and engineers. The lab provides
24/7 open access to its
state-of-the-art instrumentation including
training on instrument
operation, fabrication,
processing, characterization, and analysis of
samples as well as experiment design, even
instrument modification
if necessary.
Now, research groups Modular MuROOM at Virginia Tech
can perform tests

inside the new MuROOM environment,
which enables the research teams to reliably and accurately
conduct sensitive scientific measurements. High resolution and
atomic resolution imaging are achieved using precision instruments such as scanning electron microscopy, transmission electron microscopy and scanning transmission electron microscopy.
The VTCRI project was completed last summer. The company
designed and built a modular MuROOM in cooperation with
Magnetic Shield Ltd. UK to provide a degaussing coil system, designed to meet the specifications required by the VTCRI research
team, who needed a working environment for magnetoencephalography scanning, sensing and experimentation.
Based in the Chicago area, Magnetic Shield is a supplier and
manufacturer of specialty and proprietary magnetic shielding alloys, custom shields, test chambers, cable products and
shielding evaluation kits with worldwide presence across over 30
industries and markets of OEM manufacturers, serving electrical
and electronic engineers, physicists, scientists and other technical experts. The company also provides consulting and design
for national and government laboratories, research labs as well
as scientific, medical and engineering universities globally.
