The 6th International Diffraction-Limited Storage Ring (DLSR) Workshop, jointly organized by Kenneth Goldberg, Simon Leemann, and Elke Arenholz, was hosted by the Advanced Light Source (ALS) at Berkeley Lab on October 29–31, 2018. Approximately 160 scientists from synchrotron facilities all over the world attended the event to discuss both the technical challenges and new research opportunities at next-generation x-ray facilities enabled by multibend achromat lattices. The very low electron beam emittance that will be available at new and upgraded facilities will enable dramatic improvements in many areas of x-ray science, especially for experiments that directly require transversely coherent x-ray wave fronts, such as nanoprobe spectroscopies, coherent scattering and imaging, as well as interferometry techniques. The workshop covered topics ranging from the design, construction, commissioning, and operation of accelerators to the development of experimental systems that will be required to enable these emerging science opportunities and novel experiments that will be possible at DLSRs for the first time.
The first morning of the workshop was dedicated to presentations about planned and ongoing DLSR facility developments, including the ALS Upgrade Project (ALS-U), the upgrade of the European Synchrotron Radiation Facility (ESRF-EBS), and the upgrade to Italy’s Elettra synchrotron, dubbed Elettra 2.0. The afternoon session covered diverse research opportunities enabled by DLSRs, ranging from coherent scattering from electronic textures and soft x-ray ptychography of nanomaterials to Fourier-transform spectroscopy.
On the second day, the participants convened in two parallel breakout sessions. One breakout covered aspects of accelerator developments related to DLSRs, such as lattice design, beam dynamics, and insertion devices. The second breakout focused on experimental systems like source and beamline modeling, adaptive optics, and beam position monitors. A poster session and a workshop dinner following a spectacular sunset behind the Golden Gate Bridge rounded out the workshop program. The event concluded with reports by the breakout session leaders on their discussion and findings to all workshop participants.
The 7th International DLSR Workshop will take place in Sweden and will be hosted by MAX IV, the first synchrotron to employ the multibend achromat lattice.
