This paper presents the design of a travelling wave RF photogun operating at the European X-band frequency of 11.994 GHz. The design is based on a CLIC prototype structure milled from copper halves and uses the unique gap introduced in the geometry to couple in the laser without obstructing the outgoing electron beam. With a modest peak input power of 19 MW and a fill time of 48 ns, the gun has the ability to operate at very high RF pulse repetition rates in comparison to standing wave RF…
