7. Ball-pen probe - Wikipedia

   en.wikipedia.org/wiki/Ball-pen_probe

   Schematic picture of a single ball-pen probe. Ions (in red) have a large gyromagnetic radius and can reach the collector more easily than electrons (in blue). A ball-pen probe [1] is a modified Langmuir probe used to measure the plasma potential [2] in magnetized plasmas. The ball-pen probe balances the electron and ion saturation currents, so ...
