[TCML] Re: Breakdown voltages of toroids

[b alex pettit jr <a_pettit_jr@xxxxxxxxx>]

Hello Jim,
Thanks. This linearity is not expressed in the table attached to the
orignial email.

And, if so, why do most TC builders now use Toroidal over Spherical shapes ?

Best,
Alex P


For non-weird shapes with reasonably smooth curves, you can use the smallest radius of curvature to determine breakdown voltage. 30kV/cm is a handy approximation.

Be aware, though, that the idealized situation of a nice smooth surface and truly "free space" doesn't happen very often.
