Inquire About This Product
basic information
In recent years, the performance of electron beam devices has significantly improved, while the allowable magnetic field values have become increasingly strict. This product is a magnetic field generator that detects fluctuations in the external magnetic field with high sensitivity using a 3-axis magnetic field controller, generates a counteracting magnetic field with Helmholtz coils configured in the XYZ three axes, and is used to control and stabilize the magnetic field fluctuations inside the coils. By introducing this product, it is possible to fully utilize the performance of electron beam devices even in environments where the magnetic field is significantly unstable.
