the performance of electron beam devices has been improved remarkably.
Thus permissible limit values of magnetic fields have become strict
more and more.
This product is a magnetic field generator to provide stable magnetic
fields. It can detect magnetic field noises with a high-sensitivity
magnetic field controller, and generates a magnetic field to cancel
the noise with Helmholtz coil for three-axis (X,Y and Z).
With the introduction of this canceller, it is now possible to ensure
the full performance of electron beam devices even in places where
their magnetic field environments are extremely unstable.
