Quantum Magnetometer

High field NV Magnetometer

NV Magnetometer for high field

The High Field NV Magnetometer is an ultra-stable magnetometer that can be used to control strong magnetic fields It allows the monitoring of magnetic field fluctuations in real time.

Due to its low drift this magnetometer can be used in atomic physics experiments, MRI systems and particles accelerators.
The small dimensions of the sensor enable an easy integration it is also customizable according to the needs.

Main Advantages

Wide magnetic field range

from 1 mT to 30 mT

No need for re-calibration

Due to the intrinsic properties of NV diamonds

Stable

Due to the rejection of thermal fluctuations

Easily integrated

Due to the small size of the remote sensor

The measuring instrument

The High Field NV Magnetometer consists of a fiber optic millimeter measuring head, containing a diamond with nitrogen vacancy (NV) centers, and a control unit. The magnetic field measurement is performed by the optical detection of the electron spin resonance of the NV centers diamonds.

The communication with the control unit is done directly with a computer. The High Field NV  Magnetometer T provides an error signal relative to a magnetic field set point, which can be used to stabilize the field.
