| Popis: | The neutron beam at the FRANZ facility will be produced by the 7Li(p, n)7Be reaction using an intense 2 MeV proton beam. These protons will be accelerated from 120 keV to 2 MeV by a coupled 4-Rod-type RFQ and a 8 gap interdigital H-type structure (IH-DTL). This coupled RFQ-IH-cavity will be operated at 175 MHz in cw mode and it has a total length of about 2.3 m. The two structures (RFQ, IH-DTL) are internally coupled inductively, and consequently only one RF-amplifier providing a total power up to 250 kW is needed for operation. The IH-DTL is RF tuned together with an Al-RFQ model, before final IH-DTL installation in the FRANZ cave, while the original RFQ was already installed in the beam line. After RF power and beam tests the coupled structure will be installed and continued with RF and beam. This paper will be focused on the RF tuning process and the main results will be presented.
