Hi Steven,

The RF here is 50W forward power. There are probably a couple dB of loss due to radiation resistance, heating up of the RG-233 lead, and various other factors, but this is basically a 50W discharge.

I've taken some precautions to limit the contribution of secondary electrons to the current measurement. The target is a cylinder of graphite that has a blind hole drilled in it where the beam enters it. This should geometrically restrict the escape of most electrons. Of course, I have no good way of telling quantitatively how effective this is.
