I would appreciate knowing what filament materials and shapes you can produce. My company makes E beam tubes and I need some new materials for experimental tube designs.
And I think you have something there about the filaments.. depends on the temperature though... as to whether significant oxidation occurs. But tungsten... seems to be adversely affected operating in too high a pressure.
