Cryo-NETIC® Magnetic Shields
Fermi National Laboratory
Fabrication of the magnetic shields for the new PIP-II superconducting cryomodules at Fermi National Lab is underway. These 650 MHz beta 0.92 local magnetic shields are fabricated from our cryogenic grade of MuMETAL®, called Cryo-NETIC®, which has very high permeability at superconducting temperatures, typically 4 Kelvin (-452.47 °F). Superconducting cavities are sensitive to trapped magnetic fields in the bulk of the superconductor and can lead to significant reduction of the cavity’s efficiency or quality factor. The shield will reduce the overall field to below 500 nano Tesla (nT).
MuROOM® Compact
Sonera Magnetics
We have recently installed a Compact MuROOM®. This magnetic shield room (MSR) is designed to achieve low residual magnetic fields and high AC magnetic field shielding factors. This room is ideal for developing magnetic field sensors and conducting Magnetoencephalography (MEG) research. Sonera is developing novel sensing technology for high-performance, non-invasive brain-computer interfaces, with the goal of connecting minds and machines.
5-Layer Zero Gauss Chamber
Naval Surface Warfare Center, Carderock Division
We have recently completed a custom 5-layer zero gauss chamber of Perfection Annealed Co-NETIC® AA Alloy with custom degaussing coil to achieve low and homogenous magnetic fields inside the chamber. The shield is used for sensor performance testing at the US Navy Carderock Magnetic Fields Laboratory.
