The Advanced Technology Centre at Swinburn University located in Hawthorn, Victoria, recently constructed a Nanoplasmonics Laboratory to host sensitive EM tools, MRIs, as well as a Magnetoencephalogram (MEG).  Primary and secondary feeders were discovered within 5 meters from the west wall and 3 meters from the north wall of the ATC facility which exceeded the EMI threshold stipulated by Swinburne University. A desiel train at the Glenferrie Station within 70 meters from the ATC building produced quasi-static DC EMI interference that impacted tool performance.

A simulation study was provided to the client of the possible mitigation solutions, one of which required re-routing of the North ductbank away from the Nanoplasmonics Laboratory area.  The MRI, MEG and SEM sitting areas were in close proximity to mechanical loads causing adjacency issues unsuitable for these instruments.  Vitatech recommended shielding remediation for all state-of-the-art equipment, to lower all AC ELF and DC EMI interference emitting from electrical, mechanical, ferromagnetic masses (nearby commuter train), as well MRI and MEG emissions harmful to SEM high-resolution imaging tools.  Vitatech designed an AC ELF/DC TEM room magnetic shield with ACS that achieves 0.1 mGp-p and less in the Bx, By and Bz axis from ambient 50 Hz magnetic field sources and the nearby quasi-static DC train sources.  The AC ELF/DC magnetic shield was installed by a local Australian shielding contractor.
