  • Abstract
    Transverse emittance of field emission beam generated from single-gate FEAs are experimentally studied. Although as fabricated FEAs exhibit highly granular beam, by applying the Ne-gas conditioning method, uniform FEA beam was realized and its emittance was measured and compared with the previously measured emittance values for granular beams.
