hmmm how does cold cathode emitter doesnt consume power if electrons circulate ?

It's based on the virtual photons you guys were talking about.  Every time the field emits a virtual photon, it also pulls in a virtual anti photon from the environment.   The cold cathode MAY consume a small amount of power, but this should be offset by the gain due to the second anode.  The cusped field does the work, and the potential is not consumed, with an electret.

So you're saying to use a conductive electret for the anode of the emitter?

An electret might work as part of the emitter, but it would be better to use Farnsworth's multipactor cold cathode because you'd get more electrons to accelerate through the curved part of the tube, with the non conductive electret.  The best type of emitter is a thin film diamond layer, like is used in some of the flat panel displays such as plasma screens.  These have enough power you don't have to have a vacuum interface for the tunneling effect.  But you would have to use Helium or some gas which doesn't form negative ions.  Ions can eventually reduce an electret's charge.

I'm not very familiar with multipactor devices but if the electret's field is used for adding strength to the cathodes how will you control the on/off timing? In these devices there are 2 cathodes 1 anode in the middle and a resonant circuit that controls the potential of the cathodes ..  http://journal.borderlands.com/1988/the-farnsworth-multipactor-tube/


this device looks promising... http://en.wikipedia.org/wiki/Electron_multiplier for what I must build
