The Swedish Materials Science beamline - world leading instrument in the PETRA IV era
On 30 August, the Swedish Materials Science community concurs that a Multi-scale high-energy x-ray microscope for nanostructure dynamics in bulk materials and devices would enable excellent and relevant materials science at PETRA IV
Background
As input to the beamline portfolio design for PETRA IV, on 1 December 2020, the Swedish materials science research community submitted three Scientific Instrument Proposals (SiPs) and supported a fourth.
These 4 SiPs, together with the other 185 SiPs that DESY received, were subsequently evaluated by an independent international review panel. This review concluded the Swedish SiPs were all strong suggestions - with SiP 3 Multi-scale high-energy x-ray microscope for nanostructure dynamics in bulk materials and devices being the highest rated of all 189 SiPs.
With a deadline of 1 September 2022, DESY requested that SiP3 be elaborated.
A working group led by Prof Peter Hedström, Director of CeXS, has been undertaking a prestudy to refine this concept. A briefing was called on 30 August to present the working group's output to the Swedish research community for feedback and input.
Report on the briefing
30 researchers participated in the briefing that was held on 30 August.
Dr Ulrich Lulrich (Manager of the Swedish Materials Science beamline) presented DESY's overall plans for PETRA IV and the timeline. DESY will submit plans for the upgrade to the German authorities in September 2023. The intent is to close down PETRA III on 31 December 2026 and reopen the first trench of beamlines on 1 January 2029. The Swedish Materials Science beamline will be amongst the first trench of beamlines to go life. To operate after the upgrade, only minor retrofits to the Swedish Materials Science beamline are required because this is a new, state-of-the-art instrument. There is scope to locate SiP3 in the space currently occupied by EH2 and the P22 beamline.
Prof Peter Hedström presented the refined instrument concept for SiP.
The instrument design concept is Bragg Coherent Diffraction Imaging (BCDI). A BCDI instrument design with the PETRA IV beamline's coherence will significantly improve the spatial resolution of measurements compared to existing instruments elsewhere. Thus, materials experiments at the nano scale in bulk materials and devices will become possible - also with a high temporal resolution of the nano scale experimental data.
The temporal and spatial resolution of the BCDI and other instruments is illustrated above.
The community agreed that the working groups should continue in the direction that was presented.
