I want to characterize an electron beam using something like a CMOS-camera or maybe just a Faraday cup.
The electron energy is between 1 and 10 keV and the expected total current around 10 microA for 1 keV electrons.
Essentially I want to see whether the beam diameter is around 1 micrometer (or smaller) or much bigger than that, so I would need a resolution or pixel size around 1 micrometer.
The detector should also be reasonably cheap and should last maybe 100 hours.
Does anybody have a suggestion?
