=Minimum operating current=

*There is a minimum operating current due to need to work in the magnetic self-isolating regime [L. E. Aranchuk, A. S. Chuvatin, and J. Larour, Rev. Sci. Instrum. 75, 69 (2004)]

*For our geometry (6 mm gam, 2.5" anode and 2" cathode) and taking min voltage 60 kV, the minimum operating current will be

<math> I = 0.64 \sqrt{V} \ \ln{R_a/R_c} = 22 kA</math>
