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
High Field NV Magnetometer
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 provides an error signal relative to a magnetic field set point, which can be used to stabilize the field.
