Considering that the wind doesn't change much if at all and that the only change he mentions is temperature (runtime dependent) I have suggested to him that he look at the possibility that e-emission from the hot tungsten is responsible and that he might usefully try changing his stationary electrode material to see what effect that has. I don't think anybody has really exhaustively researched these things and I suspect that even where they have been noted, there has been a tendency to put them in the too-hard basket. I would like to think that answering these things definitively for all time is exactly why we are here. Certainly, I would expect him to investigate this fully since he is doing a PhD on the subject of TCs. I am of course saying this off the record. Regards, malcolm
