  • Abstract
    A quantum efficiency close to 1% has been demonstrated for stable and atmosphere tolerant photocathodes for a photoinjector producing short electron bunches with current 100-500 A. Experimental study of electron emission during ferroelectric polarization reversal by high voltage pulses has been performed. Emission current density reached 400 A/cm2, which was limited by space charge effects.
