| Abstract |
The Frankfurt neutron source at the Stern-Gerlach-Zentrum (FRANZ) will provide ultra-short neutron pulses at high intensities and repetition rates. The neutrons will be produced using the 7Li(p, n)7Be reaction induced by a proton beam. The 175 MHz IH-type drift tube linac with 8 gaps succeeds a 4-rod-RFQ. Together they form a coupled linac combination with a length of 2.3 m and accelerate the protons from 120 keV to 2.03 MeV. As the RF losses add up to 200 kW, the cooling of both accelerators is a central challenge. The RFQ-IH combination is powered by a radio frequency amplifier, which couples the RF power into the RFQ. The two structures are connected via inductive coupling. The initial beam operation of the accelerators is configured for 50 mA in cw mode. The IH-components were fabricated, RF tuning measurements are underway. The RFQ and the IH-DTL will be conditioned separately and then be connected, aiming for a beam operation at the end of 2014. A main challenge in fabrication was the precise welding required for the water cooled drift tubes and stems.
