A new transport line for transverse gradient undulator experiments at the JETI laser plasma accelerator in Jena

In this contribution, we describe the current status of the ongoing upgrade of an electron beam transport line employed in the successful experimental demonstration of capture and matching of a laser plasma-accelerated beam at the JETI laser facility, University of Jena. This upgrade aims at adapting the beam line to the higher electron energies achievable with the new JETI laser and enabling an experimental proof of the transverse gradient undulator concept to be performed in a collaboration between KIT and the University of Jena. The upgrade comprises the redesign of both the beam transport line magnets and of the beam optics, which will be described and discussed in detail.
