P62: A new small angle X-ray scattering instrument for the PETRA III Extension — •Jan Perlich, Jan Rubeck, Rainer Gehrke, and Sergio Funari — Deutsches Elektronen-Synchrotron DESY, Notkestr. 85, D-22607 Hamburg (Germany)

Presently PETRA III is the most brilliant storage-ring-based X-ray radiation source in the world and thereby offers outstanding conditions for experiments with X-rays featuring small beam cross sections, high degree of collimation, and a wide range of photon energies. In the next years, the experimental facilities at PETRA III will be extended to provide additional instruments for various applications. This PETRA III Extension project will accommodate the new small angle X-ray scattering (SAXS) beamline P62 which is intended to comprise the large variety of X-ray scattering methods ranging from wide angle X-ray scattering (WAXS) to high-resolution ultra-small angle X-ray scattering (USAXS) in transmission and reflection geometry. Furthermore, the new instrument shall allow exploitation of anomalous X-ray scattering (ASAXS) with all setups and provide the option for simultaneous measurement in different angular scattering regimes. Due to the high photon flux available, time-resolved experiments down to milliseconds temporal resolution will be possible. We will present the characteristics and design parameters of the instrument and give a comprehensive overview of the experimental possibilities opened with this new instrument.
