    "abstract": "In the framework of the Low Emittance Gun (LEG) project, high gradient\nacceleration of a low emittance electron beam will be necessary. In order to\nachieve this acceleration a -500 kV, 250 ns FWHM, pulse will be applied in\nbetween two electrodes. Those electrodes should sustain the pulsed field\nwithout arcing, must not outgass and must not emit electrons. Ion back\nbombardment, and dark current will be damageable to the electron source as well\nas for the low emittance beam. Electrodes of commercially available OFE copper,\naluminium, stainless steel, titanium and molybdenum were tested following\ndifferent procedures including plasma glow discharge cleaning.",
