Description

This presentation will report on the status of assembling and commissioning of the Cathodes And Radio-frequency Interactions in Extremes (CARIE) C-band high gradient photoinjector test facility and the status of high gradient testing of a 1.6 cell C-band RF photoinjector at Los Alamos National Laboratory (LANL). The construction of CARIE began in October of 2022. CARIE will house a high gradient copper RF photoinjector and other high gradient C-band accelerating structures (e.g., multi-cell cryo-cooled accelerating structures). The 50 MW 5.712 GHz Canon klystron powers the facility. The klystron was installed and conditioned in 2024. The output of the klystron is connected to a circulator that was conditioned to operate for up to 12 MW of power. The WR187 waveguide line brings the power from the circulator into a concrete vault that is rated to provide radiation protection for an electron beam powers up to 20 kW. The first RF injector that was fabricated is made of copper and does not have cathode plugs. This injector is installed at the end of the waveguide line and is under commissioning. High gradient commissioning of the photoinjector will validate operation of the CARIE facility. The status of the facility, the designs of the photoinjector and the beamline, and status of the high-power testing of the injector and other C-band components and cavities will be presented.
