RF Shield Room
The RF Shielding is a fully custom shielding option for specialized applications such as electron microscopes and physiological studies.
RF shielding is made of G60 grade, 11-gauge galvanized steel. It offers the advantages of high shielding performance, durability, and ideal electrical continuity. Each panel section provides excellent stability to airborne moistureinduced warping and structure strength that lend to its rugged structural design. |
Key Features
Pure, electrically deposited copper
RF attenuation levels of < 100 dB up to 400 MHz frequencies
Free standing, structurally isolated RF walls
Lightweight
Factory engineered and fabricated RF shield panels
Contractor friendly interiors
RF shielding has a conductive material lining which is used for attenuating EMI/RFI signals.
Typical performance, as measured in accordance with NSA 65-6/94-106/ CID 09.12, is 100 dB from 200 kHz to 1 GHz.
The specialized construction of the RF shielding also provides excellent low frequency AC magnetic field attenuation characteristics.
- Electron microscopes
- Physiological studies
- Other custom applications
Description
This modular frame construction is wrapped with electroplated copper which can conform to any design criteria. The engineered and bolted system enhances RF integrity with wide 4.4 cm (1 3/4″) seams that are highly compressed, offering a seamless shield surface. Interior fasteners do not have to penetrate the shield surface by design, which enhances the long term life of the shield.
Features
The MR-Cu Shield utilizes pure electrically deposited copper as the RF attenuator. This copper system offers superior electrical and metallurgical properties. The light weight panels further enhance constructability in any architectural design. This shielding system provides RF attenuation levels greater than 100 dB up to MR frequencies of 400 MHz (9.4 Tesla).
The free standing RF walls are an important consideration with regard to acoustic and seismic concerns. Because the walls are structurally independent from the parent walls of the MRI suite, there is an inherent acoustic envelope surrounding the room. Structurally independent walls also provide a unique seismic component and are not subjected to the same seismic forces as the parent structure.
The light weight ceiling panels (1.1 kg/sq. ft or 2.4 lbs/sq. ft.) reduce the gravity and dead loads that would be applied to the overhead structures. Additionally, overhead spanning beams can be employed without the use of heavy structural members.
Factory engineered and fabricated RF shield panels offer enormous flexibility in architectural design. Contractor friendly interiors allow for the addition of interior finishes and all utilities without penetration of the RF shield surface, assuring long term high performance.
