Popis: | Turkish Atomic Energy Authority is working on building an experimental proton beamline with local resources at the Saraykoy Nuclear Research and Training Center (SANAEM). Manufacturing of the radio frequency quadrupole (RFQ) was started after the beam dynamics and 3D electromagnetic simulation studies were performed. The vanes were machined with a three axis CNC machine. A CMM was used for the acceptance tests of the vanes and also for assembling. Production and assembly results were found acceptable for this cavity, the very first one developed in Turkey. Copper plating was performed by electroplating the aluminum vanes. The plated vanes were bolted and bonded with eight screws, eight pins and two different adhesives. A silver paste was used for RF sealing and a low vapor pressure epoxy was used for vacuum isolation. First LLRF tests of the RFQ were done with a bead-pull setup and a VNA. A N-type RF coupler and a pick-up were used for the LLRF tests. Phase shift method was used for the bead-pull tests. Cavity quality factor was measured with 3dB method for different RF sealing stages. This study summarizes the machining, assembling and the first LLRF tests of the SANAEM RFQ.
