Experimental studies of dark current in a superconducting rf photoinjector

A superconducting rf photoinjector (SRF gun) has been put in operation successfully at the radiation source ELBE. It produces a 13 MHz, low emittance, cw beam with beam current up to 400  μA and energy of 3 MeV. During the gun operation, the field emission from the niobium cavity and the Cs_{2}Te ca...
