A superconducting transversal gradient undulator (TGU), tailored to the particular beam properties of the laser wakefield accelerator (LWFA) at the University of Jena, has been designed and constructed at KIT. This undulator in combination with a specialized beam transport line will be employed to produce undulator radiation with natural bandwidth despite the relatively large energy spread of the electrons produced by the LWFA. The fabrication of this undulator and first results of the magnetic field measurement are discussed in this paper.

The transport and matching of electron beams generated by a laser wakefield accelerator (LWFA) is a major challenge due to their large energy spread and divergence. Strong focussing magnets and a chromatic correction are required. This contribution discusses the layout of the beam transport optics for a diagnostic beamline at the LWFA in Jena, Germany. The aim of this optics is to match the betatron functions and the dispersion to the field of a transverse gradient undulator (TGU) such that monochromatic undulator radiation is generated despite the large energy spread.
