AbstractAbstract
[en] RF cavities for photocathode RF gun were built and tested by using high power RF up to 27 MW. The electric field gradient on the cathode reached 140 MW/m. During the RF conditioning, dark currents were measured for cavities with different surface treatments. A laser pulse was irradiated on a copper cathode and the photo-emitted beam was accelerated up to 3.2 MeV. An effective quantum efficiency of the cathode was obtained by changing laser power and field gradient. (author)
