A new transport line for transverse gradient undulator experiment at the JETI-200 plasma accelerator — •Maisui Ning1, Samira Fatehi1, Kantaphon Damminsek1, Axel Bernhard1, and Anke-Susanne Müller1,21LAS,KIT,Karlsruhe — 2IBPT,KIT,Karlsruhe

The Karlsruhe Institute of Technology (KIT) and the University of Jena develop the generation of monochromatic undulator radiation with laser plasma-accelerated electron bunches by using a transverse-gradient undulator (TGU) designed to compensate the electron bunch energy spread. A proof-of-principle experiment with a superconducting TGU prototype, employing a specially designed beam transport line, is under preparation. A first experimental test of this transport line has been performed and evaluated. In this contribution, we describe the current status of the redesign of the beam transport line magnets and the beam optics, considering the results of this test as well as of the ongoing characterization experiments for both, the electron beam and the TGU, to prepare the experiment with the TGU at the laser-plasma accelerator setup at the JETI-200 laser facility in Jena.

This work is supported by the BMBF project 05K19VKA PlasmaFEL (Federal Ministry of Education and Research).
