	Funding: Supported by DFG, BMBF, and the Federal State NRW Since 2011, a new Coherent Harmonic Generation (CHG) source* is under commissioning at the 1.5 GeV storage ring DELTA. Following first experiments using the fundamental wavelength of a Ti:sapphire laser for seeding a non-symmetrical optical klystron, 400 nm pulses from a second-harmonic conversion unit (SHG) are used since early 2012. With the radiator tuned to the second harmonic thereof, 200 nm CHG pulses are routinely observed. In order to detect higher harmonics and to proceed to a seed wavelength of 266 nm, an evacuated diagnostics beamline is under construction. Additionally, an existing VUV beamline is being upgraded to allow for the detection of the CHG pulses and their utilization in pump-probe experiments. Furthermore, a dedicated THz beamline provides valuable information about the laser-induced energy modulation of the electrons. In this paper, the status of the project and technical details will be presented. * Huck et.al., FEL 2011

Since 2011, a new Coherent Harmonic Generation (CHG) source* is under commissioning at the 1.5 GeV storage ring DELTA. Following first experiments using the fundamental wavelength of a Ti:sapphire laser for seeding a non-symmetrical optical klystron, 400 nm pulses from a second-harmonic conversion unit (SHG) are used since early 2012. With the radiator tuned to the second harmonic thereof, 200 nm CHG pulses are routinely observed. In order to detect higher harmonics and to proceed to a seed wavelength of 266 nm, an evacuated diagnostics beamline is under construction. Additionally, an existing VUV beamline is being upgraded to allow for the detection of the CHG pulses and their utilization in pump-probe experiments. Furthermore, a dedicated THz beamline provides valuable information about the laser-induced energy modulation of the electrons. In this paper, the status of the project and technical details will be presented.
