Description
Two high-gradient 1.6-cell normal-conducting RF photoinjectors at C-band were designed for operation at the Cathodes And Radiofrequency Interaction in Extremes (CARIE) facility at Los Alamos National Laboratory (LANL). The first photoinjector cavity uses a planar copper cathode and has been fabricated and tuned at low power. The second photoinjector cavity was designed for using INFN-style photocathode inserts and is currently under fabrication. The high-power RF system of CARIE comprising a 50-MW 5.712-GHz klystron, circulator, and waveguide line has been conditioned to providing 12 MW with 1-µs pulse length.
