PETRA IV extends the X-ray view to all length scales, from the atom to millimetres. Researchers can thus analyse processes inside a catalyst, a battery or a microchip under realistic operating conditions and specifically tailor materials with nanostructures.

PETRA IV – The ultimate 3D process microscope has the potential: to address individual organelles in living cells and follow metabolism pathways with elemental and molecular specificity to image the chemistry inside a battery down the atomic level and …

Using the ultrabright X-ray light, researchers want to investigate natural phenomena and technical processes in new dimensions – from the millimetre range down to the nanoscale. PETRA IV will provide insights and knowledge and help to clarify urgent questions for the future:

PETRA IV will provide high-precision analytics for the ‘observation, design, and control’ of matter and processes - from atomic dimensions to the macroscopic world and on time scales from nanoseconds to hours.

The PETRA IV machine project aims at the construction of an ultra-low emittance storage ring delivering operating at 6GeV with a 20 pm emittance, to be installed in the ex-isting 2.3 km PETRAIII tunnel. Significant changes to the machine concept were made since the CDR [1]. The PETRA IV complex will reuse the existing LINAC-II (450

The PETRA IV project aims at upgrading the present synchrotron radiation source PETRA III at DESY into an ultralow-emittance source. Being diffraction limited up to X-rays of about 10 keV, PETRA IV will be ideal for three-dimensional X-ray microscopy of …

The facility, called PETRA IV, will provide 3D images of the nanocosm and offer insights into materials and biological structures with unprecedented precision – from the structure of pathogens, through catalysts, to innovative microchips and quantum materials.

In PETRA IV storage ring the beam lifetime is dominated by Touschek-effect. Even if we provide >7% rf acceptance, the local momentum acceptance (LMA) determines the upper limit due to strong nonlinearity.

Important research fields and technology trends that can be investigated with the planned portfolio of beamlines at PETRA IV. The overview shows how the various techniques and beamlines can be used for all challenges in the key technological areas.

Being diffraction limited up to X-rays of about 10 keV, PETRA IV will be ideal for three-dimensional X-ray microscopy of biological, chemical and physical processes under realistic conditions at length scales from atomic dimensions to millimetres and time scales down to the sub-nanosecond regime.
