Latest Patents

Cattelino's latest patents include a method and apparatus for magnetic focusing of off-axis electron beams. This innovation provides axially symmetric magnetic fields around the longitudinal axis of each beam in a multi-beam electron beam device. The magnetic field symmetry is independent of beam voltage, beam current, and applied magnetic field strength. A flux equalizer assembly is strategically placed between the cathodes and anodes, near the cathodes of the device. This assembly features a ferromagnetic flux plate that is entirely contained within the magnetic focusing circuit. The flux plate includes apertures for each beam, and it incorporates flux equalization gaps that create perturbations in the magnetic field. These gaps counteract the asymmetry caused by the off-axis position of the beam. The design effectively prevents or significantly reduces beam twist, ensuring that all electron beams remain linear.
