2005 I 2
From QED
-3 V
Drawing a tangent from the zero crossing to the ion saturation current level (-1 mA) gives roughly -2 V, so the electron temperature is 2 eV.
Argon ions will probably be singly charged, since the second ionization potential is significantly over 1.5 eV
The ion saturation current is -1 mA. since:
One finds (assuming the mass of argon is 36):
The electron saturation current is:
We get:
So that the current is:
This beam electrons have velocity:
The beam would increase the current for V > − 10V uniformly by:
