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 …

2025年2月25日 · Using the ultrabright X-ray light, researchers want to investigate natural phenomena and technical processes in new dimensions – from the millimetre range down to …

This new paradigm is about using accumulated knowledge in a targeted way to actively design and control systems. PETRA IV will provide high-precision analytics for the ‘observation, …

2025年2月25日 · Mit dem ultrahellen Röntgenlicht wollen Forschende Naturphänomene und technische Prozesse in neuen Dimensionen untersuchen – vom Millimeterbereich bis hinunter …

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 …

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, …

2024年8月15日 · The PETRA IV project for upgrading the 2.3 km 6 GeV PETRA III storage ring to a diffraction-limited synchrotron radiation source is nearing the end of its detailed technical …

DESY is planning the upgrade of PETRA III to a fourth-generation light source, providing high brightness, quasi diffraction limited hard X-ray photons. The project is un-derpinned by the …

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 …

2020年12月1日 · With the current design of the PETRA IV storage ring, many beamlines will gain both in brightness and in flux, as the electron beam emittance is significantly reduced and the …
