No biggie Dud, My figures indicated that the focal spot of the electron beam, whatever size it actually is,? is approximately 1" from the outer edge of the brass collimator on the outer housing, and that sounds credible.

Geo,
I have the specs here someplace but I don¡¯t remember exactly. 16
seems about right and the microfocus spot was very small as I remember.
I¡¯ll dig around and see f I can find the manual
?

That
sounds logical Dud, hey on your Kevex stand alone tube, do you know the spot
size and the cone angle? The one in my rig here in the counting room seems to
have a 16 degree cone- does that sound right?
