Hirsch did it.

Hirsch did it with the Farnsworth Fusor
he was running experimental test studies on.
He used six diametrically opposed ion guns,
each with a maximum current of 10 mA.

Yep, it has been done before.
>Actually, I was thinking, if you make the smallest possible grid that can still do the job and will last just long enough, you could reduce strikes against the grid and increase circulation further and if for just a few minutes, you might just get to higher reaction rates.

What exactly do you mean by the
"smallest possible grid"?

I'm not sure I understand your idea how
a smaller grid is going to increase
recirculation. Please explain.

>Just some ideas.
Good ideas. Great minds think alike.
