As part of the PETRA III extension, DESY is planning to build an X-ray spectroscopy beamline (P22) within the scope of the India-DESY collaboration, serving different spectroscopy techniques. One experiment hutch will accommodate instruments for Hard X-Ray photoelectron spectroscopy (HAXPES). Currently, a very successful HAXPES instrument is being operated at beamline P09 sharing the beamtime with two resonant X-ray scattering instruments. It is planned to relocate the HAXPES activities to the new undulator beamline P22 in PETRA III extension hall East.

Two endstations are planned in the HAXPES hutch of P22:

  • a HAXPES setup with a SPECS 225HV spectrometer equipped with a ±30° wide-angle lens, improved high voltage supplies and a delayline detector or multichannel spin detector. This instrument is part of a collaboration between University of Würzburg (R. Claessen), University of Mainz (G. Schönhense) and DESY and is partly funded by BMBF.
  • downstream, research center Jülich (C.M. Schneider) is planning to install a
    NanoESCA PEEM instrument optimized for hard X-rays ("HAXPEEM").

The workshop aims at discussing the technical design of the beamline and instrumentation including control software and other requirements with the user community. The outcome of the discussion will be the basis for finalizing the specification of the beamline.
First beam at the new beamline is planned in late Spring, 2016.

in addition to the workshop program, there will be a discussion round on experiment control software concepts including remote control of electron analyzers for HAXPES (Friday morning, July 4).  If you are interested to participate, please send an e-mail to the organizer.
