The ability to operate plasma targets with high repetition rate is a key element for reproducible LWFA performance and experiments with good statistics. Here, we show the design and commissioning results for a target setup using a capillary-type plasma target and a differential pumping scheme, implemented at the LUX Beamline for plasma-driven undulator radiation. We show continuous flow operation with target pressures of up to 400mbar and 5Hz electron generation. With this system, the electron repetition rate is only limited by the repetition rate of the laser.
