Magnetic Field Compensation System MR-3
Have you ever operated a high resolution electron microscope near an elevator
or in the vicinity of cables carrying high AC currents? Then you probably
know what magnetic noise is! The magnetic field compensation system MR-3
is a proven solution of problems related with magnetic field noise in the
frequency range from DC to ~1000 Hz. Typical applications are noise reduction
in electron microscopy, electron and ion beam experiments, magnetic resonance
imaging (MRI), biomagnetic investigations, SQUID operation, and paleomagnetic
research.
The magnetic field is measured with a low noise triaxial fluxgate magnetometer.
Three power amplifiers are built in for direct connection of compensation
coils. Typically, such coils consist of a set of cable rings installed
in the edges of the laboratory. For example, pairs of 5-wire 2.5 mm²
cable rings connected in series can be used to compensate for magnetic
field noise up to 5 µT (peak to peak) in a laboratory of 6 x 6 m²
base dimensions. Custom modifications, compensation coils, and installation
service are available on request.
