Petra III is the new German 6 GeV synchrotron source with an emittance of only 1 nm rad. This makes PETRA III ideally suited for experiments requiring nanometer beam sizes in the harder X-ray regime. 14 different endstations cover experiments from material- to life sciences. The storage ring has reached its full performance and 3 beamlines have started regular user operation already.
Beamline P11 is dedicated to the structure determination of biological objects in two different modalities. A Scanning Transmission X-ray microscope (STXM) operated at X-ray energies between 2.4 and 10 keV will allow structural investigations of aperiodic objects such as single cells and also small tissue sections. The STXM will allow cryo-cooling of the samples and will be operated in vacuum. A crystallography endstation will provide beamsizes down to 1 micron for the investigation of micro crystals and also a parallel beam option for large unit cell systems. The experiment will be equipped with a Pilatus 6M detector and an automatic sample changer.
The first part of the presentation will provide a general introduction to the PETRA III facility and its beamlines. In the second part, beamline P11 will be presented in more detail with emphasis on different high precision hardware components developed by our group.
