“…35,36 This scientific effort of producing shorter wavelength and duration radiation pulses is driven by many potential applications in fundamental science, medicine and industry . [37][38][39] For example, structural and physical state evolution in pump-probe experiments of materials and bio-samples may have a time span of tens of femtoseconds (10 −15 s), and even more fundamental processes such as ionisation, isomerization, and ultrafast charge transfer in atoms, molecules, and nanostructures can occur on timescales down to the attoseconds (10 −18 s) . [40][41][42] The underlying fundamental principle of radiation generation is based on utilizing electrons or electron beams of modest to ultrarelativistic energies in various ways to emit radiation at the desired wavelength.…”

We provide a pathway to compact ultrabright light sources, based on ultrabright, high energy electron beams emerging from a combination of plasma wakefield acceleration and plasma photocathodes. While plasma acceleration is known to produce accelerating fields three or four orders of magnitude larger than conventional accelerators, the plasma photocathode allows production of electron beams three or four orders of magnitude brighter than conventional, and thus is suitable to unleash the full potential of plasma accelerators. In particular, this is the case for various types of light sources, which profit enormously from an increased electron beam brightness. Building on the recent first experimental demonstration of the plasma photocathode, in this work we discuss the prospects of plasma photocathodes for key photon source approaches such as x-ray free-electron lasers, betatron radiation, ion-channel lasers and inverse Compton scattering.

“…This very bright light is emitted tangentially to the direction of the circulating electrons’ motion. Synchrotron radiation was first observed in 1947 at the General Electric laboratories in the United States (Robinson, 2009), and its usefulness for condensed matter research was first recognized in the late 1960s. Since that time, there has been explosive growth in the use of SR for research applications.…”

To understand the biogeochemistry of nutrients and contaminants in environmental media, their speciation and behavior under different conditions and at multiple scales must be determined. Synchrotron radiation‐based X‐ray techniques allow scientists to elucidate the underlying mechanisms responsible for nutrient and contaminant mobility, bioavailability, and behavior. The continuous improvement of synchrotron light sources and X‐ray beamlines around the world has led to a profound transformation in the field of environmental biogeochemistry and, subsequently, to significant scientific breakthroughs. Following this introductory paper, this special collection includes 10 papers that either present targeted reviews of recent advancements in spectroscopic methods that are applicable to environmental biogeochemistry or describe original research studies conducted on complex environmental samples that have been significantly enhanced by incorporating synchrotron radiation‐based X‐ray technique(s). We believe that the current focus on improving the speciation of ultra‐dilute elements in environmental media through the ongoing optimization of synchrotron technologies (e.g., brighter light sources, improved monochromators, more efficient detectors) will help to significantly push back the frontiers of environmental biogeochemistry research. As many of the relevant techniques produce extremely large datasets, we also identify ongoing improvements in data processing and analysis (e.g., software improvements and harmonization of analytical methods) as a significant requirement for environmental biogeochemists to maximize the information that can be gained using these powerful tools. Core Ideas SR‐based techniques have revolutionized the field of environmental biogeochemistry. Improvements to light sources will provide SR with extreme brightness and coherence. This should be met with similar advances to synchrotron‐related hardware and software. Environmental biogeochemists can drive the new advances in the synchrotron science. Advances in SR will enable future breakthroughs in environmental biogeochemistry.

“…Retracing the evolution of the DSE, crucial importance has been attributed to the generation of smart algorithms and the advancement of computational methods. However, it is also necessary to mention the essential connection to the devel-opment of neutrons and light sources in the last 50 years (Mason et al, 2013;Robinson, 2015;Bras et al, 2014;Pellegrini et al, 2016). The tunable energy of modern sources, while offering the possibility of reducing sample absorption or enhancing element-specific details by, respectively, avoiding or exploiting absorption edges, crucially contributed to boost the use of the method introduced by Zernike and Prinscommonly referred to as Pair Distribution Function (PDF) analysis (see e.g.…”

Debye's scattering equation (DSE) has spanned a century of scientific development, from the dawn of quantum mechanics and the investigation of the structure of atoms and molecules to the era of nanotechnology, paving the way tototal scatteringmethods. The formulation offers the most accurate representation of the intensity scattered by randomly oriented atomic aggregates, constructed by superimposing the signal from each atomic distance in the molecule. The present paper reviews some of the milestone applications, from the interpretation of the intensity curves from gases and vapours, to aggregates of increasing size and more extended order. Important developments, aimed at mitigating the prohibitive computational complexity of the DSE, and state-of-the-art methods for the characterization of static and dynamic displacements are also discussed.
