Duke University CIEMAS

CIEMAS is a four building, 322,000 sq. ft. research center located at the Duke University Edmund T. Pratt Jr. School of Engineering that focuses on the fields of photonics, bioengineering, communications, and materials science and materials engineering. Vitatech was retained by Zimmer, Gunsel, Frasca (ZGF) to assess the potential EMI/RFI impact from main electrical distribution room (i.e., switchgears, transformers, ATS’s, distribution panels, etc.), passenger elevators, WiFi/ Cellular/Broadcast RFI emissions on the two proposed SEM and TEM tool rooms in the CIEMAS center. Vitatech surveyed the future clean-room and imaging tool areas and recommended two high-performance AC ELF Magnetic Shielding Systems for the SEM and TEM tool rooms to guarantee very low levels for the life of the building.

Vitatech then designed, fabricated and installed two high-performance AC ELF Magnetic Shielding Systems for the future FEI Titan TEM and SEM tools. Final EMI Commissioning was performed and verified compliance to the 0.1 mGp-p (Bx, By and Bz axes) magnetic flux density performance requirement under all normal and peak loads building loads.
