A 40-period superconducting transverse gradient undulator (TGU) has been designed and fabricated at Karlsruhe Institute of Technology (KIT). Combining a TGU with a Laser Wakefield Accelerator (LWFA) is a potential key for realizing an extremely compact Free Electron Lasers (FELs) radiation source: LWFAs have an unprecedentedly high longitudinal electric field inside the laser-driven plasma wave; the TGU scheme is a viable option to compensate the challenging properties of the LWFA electron beam in terms of beam divergence and energy spread. In this contribution, we report on the operational experience of this TGU inside its own cryostat and show first results of the characterization measurement and the further plan for experiments at the SINBAD Facility (DESY, Hamburg) and the JETI200 Laser laboratory in Jena.
