It is shown in this response that the radiated power from an intense beam of accelerating electrons can be a sizable fraction of the total injected power. Further, it is argued that the association of an effective electrostatic potential with the real voltage drop across an open diode can either lead to the unphysical consequence that accelerated electrons do not radiate or to the unreal situation in which the diode must be considered closed. Rather, it is shown that in the real scenario, the entire energy (or applied potential) is fed to the diode region, one part of which results in energy gain of the electrons and another that leaks out as radiated energy from the opening in the diode region.
