2nd Meeting on Future XFEL Optics

"Damage threshold of mirrors and multilayers"

Date: 23. - 24. November 2006
Location: Institute of Physis, Czech Academy of Science, Prague
Organisers: K. Tiedtke, H. Wabnitz

X-ray optics at the European XFEL will have to fulfil extreme requirements in terms of figure and roughness errors, wavefront preservation, and stability. Furthermore, the particular properties of the European XFEL with up to 3000 pulses in a period of 0.6ms and a peak power of the individual pulses in the GW range request a high long-term stability of optical elements. The influence of the ultra-short and intense X-Ray radiation pulses may damage due to ablation processes or thermal fatigue or at least degrade the optical properties of coatings and substrates.

In order to start a research and development program for XFEL optics a workshop series has been initiated by H. Wabnitz and K. Tiedtke (DESY). This series provides amongst other the possibility to review current state of the art technologies, to define development projects and experimental campaigns, and to discuss further steps to develop beam transport and focusing optics fulfilling the extreme requirements of the XFEL."
