[sudo-discuss] [CCL] Free Scanning Electron Microscope in Pleasanton! (was Fwd: [Microscopy] viaWWW:SMI3200 FIB system looking for a good home)

[Adam Munich]

Aren't there plans to build a large polycarbonate box for sensitive bio
work? (I might have misheard, who knows)

If so, it makes sense to put the ebeam in there too, to take advantage of
its 4nm resolution clean air would be ideal.

Hm - "refurbished by refilling the reservoir with Gallium". That sounds
like a DIY job if I ever heard one! I happen to have some Gallium sitting
right here...
