ABSTRACT:
A virtual remote cathode has the position of a space charge cloud associated with it fixed by the geometry of a fixed insulating plate. The plate can be made to accurate dimensions and hence the cathode to control grid dimension can be accurately controlled and will not change as a result of any mechanical, electrical or physical changes in the construction. The fixed insulating plate is located on a surface of the control grid facing the cathode.
