Magnetic Field Shielding

TEM Shielded Room

IT STARTS WITH DESIGN

Early engagement with us is key. We can assist in the design which will give you the best starting point for the project.

PASSIVE SHIELDING, CONSTANT PROTECTION

A passive shield of high-permeability material attenuates both AC and DC magnetic fields continuously. With no power, sensors, or response time it provides a stable baseline environment around the microscope.

ACTIVE CANCELLATION SYSTEM

An active system measures the residual field in real time and drives compensation coils to cancel it, targeting the very low-frequency disturbances such as passing lifts, vehicles, and mains harmonics that the passive shielding attenuates least.

COMBINED SYSTEMS, COMPLETE SOLUTION

Together, the two approaches cover each other’s weaknesses. This ensures image quality is maintained even as the building environment changes around the instrument.

See it clearly

Global EMC’s TEM shielded rooms are purpose-built rooms or laboratories designed specifically to shield sensitive TEM microscopes from 50 Hz AC and Quasi-DC interference. Through passive shielding and an active cancellation system, a magnetic field shielded room is created to ensure the microscope can work to its greatest potential.

Global EMC is the industry expert in providing room shielding for TEM microscopes using our specially developed shielding technology

KEY FEATURES

Active magnetic field cancellation

A real-time compensation system with sensors and coils that detects and counteracts fluctuating magnetic fields before they disturb the electron beam.

Passive magnetic field shielding

A high-permeability alloy enclosure surrounding the instrument attenuates low-frequency magnetic fields

Shielded door

An RF-tight, sealed door that preserves enclosure integrity while allowing access for the instrument and operators.

Filtered power and signal penetrations

Power filters and shielded entry points that let cables and services enter without carrying interference into the room.

Vibration and environmental control

Isolation from vibration, along with stable temperature and airflow, to maintain the conditions these high-resolution instruments demand.

CHOOSE THE ROOM FOR

50 Hz

Shielding is required to protect transmission electron microscopes from the effects of high levels of magnetic fields.

Magnetic Field

Optimised shielding for power frequencies (50 / 60 Hz) to prevent exposure to potentially harmful levels of magnetic fields.

Quasi-DC

EMI / EMF shielding from Quasi-DC current interference.

Sensitive Equipment

Enclosed magnetic shielding for the specific use of transmission electron microscopy.
