The functioning of an accelerator relies on the ultra-precise control of hundreds of magnets. Although every magnet is a single point of failure, around-the-clock operation has to be assured for months at a time, often with a lifespan of decades. 

A particle accelerator uses magnets to steer beams of charged particles in myriads of ways: cyclotrons confine particles to a spiral path while they accelerate; bending magnets force particles to make a turn; focusing magnets refocus a diverging beam; switching magnets extract batches of particles out of a beam; wigglers cause particles to emit light; and so forth. The fact that accelerators all over the world can operate reliably for years or decades is a tribute to human ingenuity – and to good magnetometers!

Particle accelerators: the standard for thirty years

Metrolab is the only supplier of a complete range of industrial-quality, high-precision magnetometers in the extremely demanding environment of particle accelerators.

Our NMR precision magnetometers are the ultimate instruments for calibration, real-time field control, and dipole mapping; whereas our digital integrators have entered history as the reference for more difficult magnet mapping jobs. For two decades, accelerator operators and particle physicists have relied on our equipment to get and stay operational.

Accelerator operators

Mapping magnets prior to installation, calibrating reference magnets for a variety of measurement techniques, real-time control of beam bending magnets, integrating voltage measurement to compute a flux: Metrolab systems support accelerators operator in their daily and most advanced tasks.


Leveraging these two decades of experience in leading laboratories throughout the world, we enable scientists to focus on the essence of their research. Our customers benefit not only from our industrial quality products, but also from our know-how in the areas of high precision and high field magnetic measurement and mapping.
