Abstract
Technology is described for an electron gun driver including a half bridge driver circuit and a drive controller. The half bridge driver circuit includes a drive circuit configured to generate a grid drive voltage for a grid connection of an electron gun, and a cutoff circuit configured to generate a grid cutoff voltage for the grid connection of the electron gun, and a gate driver configured to switch between the grid drive voltage and the grid cutoff voltage. The drive controller is configured to generate a pulse input to the drive circuit and cutoff circuit and grid switching signals for the gate driver.
