Abstract: Gun5, the new generation of normal-conducting 1.3 GHz RF guns for high-gradient and long-pulse operation at DESY’s linac driven free-electron lasers is in operation at PITZ and European XFEL. The improved gun de-sign allows for RF pulse durations of up to 1 ms at 10 Hz repetition rate, at gradients of ~60 MV/m at the cathode. Special features are two redundant RF pickups for RF regulation and a symmetric power coupler to reduce RF asymmetries. Four cavities of the Gun5 type have already been produced, and three of them have been tested at PITZ. Two guns are currently in operation at PITZ and the European XFEL. This article will give an overview on the operation experiences with these gun cavities.
