Approaches towards a linear terahertz accelerator technology for compact X-ray sources are discussed. The use of very high frequencies enables operation of accelerators at higher field strength with low energetic driver pulses. First experimental results on laser based high energy terahertz generation, terahertz guns and accelerators are demonstrated. The high acceleration fields and gradients possible in terahertz devices enable novel electron bunch manipulations, bunch diagnostic and promise ultimately fully coherent X-ray production from compact sources. Theoretical calculations and experimental implementations of X-ray sources based on this technology will be discussed.


Franz Kärtner received his MS and PhD degrees from Technical University of Munich and the Venia Legendi in Experimental Physics from ETH Zurich. He was on the faculty of Karlsruhe Institute of Technology and Massachusetts Institute of Technology before joining DESY and Universität Hamburg in 2011. He is a fellow of OSA and IEEE.
