A new X-ray undulator beamline dedicated to HAXPES applications is currently being constructed at PETRA III making use of the high source brilliance. The beamline is located in the recently built Ada Yonath experimental hall and is expected to get first light for commissioning in October this year. It will be available for user proposals from fall 2018 (proposal submission March 1, 2018).
This dedicated HAXPES beamline comprises a selection of techniques using specialized instruments built and operated in collaboration with external user groups. These include HAXPES with optional multi channel spin detection using a 2D spin filter, HAXPEEM, k-space microscopy and high-pressure HAXPES. All current HAXPES activities at beamline P09 will be relocated to the new beamline.
The opportunities offered by P22 will be presented and discussed in this workshop.
Looking further into the future (~10 years ahead), DESY is currently preparing a proposal for a major facility upgrade, “PETRA IV”, which will be a completely new multi-bend achromat 6 GeV machine with an horizontal emittance down to ~10pm rad yielding a diffraction limited beam up to 10 keV photon energy. The new facility is also planned to provide additional beamlines for techniques making use of the extreme source brilliance.
In view of this development, the workshop should also address and identify potential new technical and scientific directions for tender and hard X-ray photoelectron spectroscopy and microscopy which could become feasible with such a powerful source.
