  The European-XFEL injector hosts a third-harmonic section composed by a module with eigth 3.9 GHz cavities equipped with a coaxial frequency tuner inspired by INFN-LASA Blade Tuner design. The 3.9 GHz tuning system met specifications during all the injector runs in 2016 up to the recent commissioning of the entire linac; it matched the required tuning range and frequency sensitivity although higher than expected cavity detuning was experienced during pressure transients in the cryogenic system. An analysis of all collected experimental data is reported in this paper together with the strategy developed to provide a sound and effective retuning routine to the control room operator.

  The E-XFEL injector was commissioned and operated with beam in 2016. Part of the injector is a third harmonic system of 8 SRF cavities operating at 3.9GHz. This paper describes all aspects of the commissioning and operation of the third harmonic system with beam.
