Experimental study of the reduction of field emission by gas injection in vacuum for accelerator applications
Field emission current from surfaces under vacuum and at high field strengths can be reduced by the injection of gas into the evacuated volume. In this paper, the effects of H_{2}, He, N_{2}, and Ar on this “dark” current emitted from a tungsten carbide point cathode for 2 cm gap distance is studied...
