Electron beam control in a scanning electron microscope

I describe electron beam optics and deflection as they are employed in scanning electron microscopy.

    I've got an electron microscope gun and lens assembly. The filiment is busted, but if you would like to bust open the assembly and tinker some time I would love to make a road trip out of it!

    I've also got the sample chamber. I am gutting the chamber to use as a vacuum chamber, so the plate that controls x,y,x,r,o is all yours if you want it

    Hey guys, love the electron microscope.I've only been tinkering with electronics for 3-4 of year and I want to make one so bad, don't think I'm skilled yet to make one. Maybe one day I will get started I'm only 16 so got lots of time.

    Now I want to build one of these and see if it can do E-beam lithography... But another project is not what I need right now.
