Computational Studies for the Future EEHG Upgrade at DELTA Short-pulse Facility — •Arjun Radha Krishnan, Benedikt Büsing, Arne Held, Shaukat Khan, Hubertus Kaiser, and Carsten Mai — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

The short-pulse facility at the 1.5-GeV synchrotron light source DELTA, operated by the TU Dortmund University, currently employs the Coherent Harmonic Generation (CHG) technique to generate ultrashort VUV pulses. This will be upgraded to Echo Enabled Harmonic Generation (EEHG) scheme to reach even shorter EUV wavelengths in the future. The two-stage energy modulations in combination with two dispersion sections allow more flexibility towards optimizing the parameters for the setup.

Results of the computational studies regarding the optimization of undulator, laser, and chicane parameters with an aim of producing coherent emission at 20 nm (40th harmonic of seed wavelength) will be presented.

This project is funded by BMBF under contract 05K19PEB.
