A high brightness electron beam produced by a ferroelectric cathode
We report experimental measurements of the brightness of an electron beam produced by a ferroelectric cathode. The brightness value of B/sub n/ = 1.2x10/sup 1/1 A/m/sup 2/ rad/sup 2/ for a 15A, 1OkV beam exceeds that obtained from thermionic cathodes operating at comparable voltages. To our knowledge, these are the first reported measurements of the beam quality (emittance and brightness) of the electron beam from a ferroelectric cathode.<>
