N2 - To meet the demand for intense highly charged stable ion beams for medical and nuclear physics a traveling-wave-tube (TWT) based RF generator has been installed and is in commissioning at the Advanced Electron Cyclotron Resonance Upgrade (AECR-U) ion source at the UMCG-PAR-TREC facility. The generator comprises 2 x 750W in-phase combining TWT RF generators with an output frequency range of 12.75-14.5 GHz. Frequency scanning routines have been incorporated in the control software which makes it possible to identify intense and stable ion-beam regimes within the plasma-heating frequency domain. The new RF generator replaces a 14.1 GHz fixed frequency klystron. In this paper we present the setup, the scanning methodology, the first measurements, and discuss the frequency scans measured from a helium and a xenon beam. These results improve the stability and increase the beam intensity at the UMCG-PARTREC facility.
