摘要:
A mechanism is proposed to greatly increase the space charge limiting current. It consists of making use of the negative ponderomotive energy of some appropriate cavity mode to thwart the buildup of the beam electrostatic energy. For present microwave technology, the calculations show, for instance, that a 70% increase in the limiting current of a 250 kV relativistic electron beam looks achievable.
