These spheres will be inside a larger surrounding vacuum chamber, right?

(3/8" thick borosilicate glass) I intend to use a single board B&W video camera for remote observation of the poissor. I am a little concerned about the neutrons and the CCD element. At lower fusion levels, this might not be a hassle.

Why not put a mirror to bend the optical path and keep the ccd out of "line of sight" with the port (at least the gammas and xrays won't hit it then). I assume the plasma is pretty bright, so a long focus lens could also be used to get some distance. A cheap telescope would work. Many of the inexpensive CCD cameras have a scan reverse, if L-R reversal is an issue.
