Inverse pulse control for eddy current abatement
Abstract:
The present embodiments are directed towards the abatement of eddy currents that develop in a conductive material as a result of rapidly switching the magnitude of a magnetic flux proximate the material. For example, in one embodiment, a system having a controller is provided. The controller is configured to apply voltage pulses to a magnetic coil, the magnetic coil being operable to steer an electron beam within a housing comprising conductive material. The voltage pulses include a first pulse configured to cause the magnetic coil to switch from generating a first magnetic flux to generating a second magnetic flux, and a second pulse configured to induce a first eddy current having substantially the same directional orientation as the first magnetic flux.
