High Brightness Coherent X-ray Sources by High-Order Harmonic Generation and Parametric X-ray Amplification
The development of high-order harmonic (HH) generation at GSI aims at creating a seed source for soft X-ray lasers (SXRL) that are based on amplification of spontaneous emission. It has been demonstrated that a seeded SXRL possesses a higher beam quality in terms of spatial homogeneity and spatial coherence [1]. In combination with the narrow spectral bandwidth, seeded SXRL represent attractive...
متن کاملPlasmon-enhanced photocathode for high brightness and high repetition rate x-ray sources.
In this Letter, we report on the efficient generation of electrons from metals using multiphoton photoemission by use of nanostructured plasmonic surfaces to trap, localize, and enhance optical fields. The plasmonic surface increases absorption over normal metals by more than an order of magnitude, and due to the localization of fields, this results in over 6 orders of magnitude increase in eff...
متن کاملData science skills for referees: I Biological X-ray crystallography
Since there is now a growing wish by referees to judge the underpinning data for a submitted article it is timely to provide a summary of the data evaluation checks required to be done by a referee. As these checks will vary from field to field this article focuses on the needs of biological X-ray crystallography articles, which is the predominantly used method leading to depositions in the PDB...
متن کاملThe X-ray Transform and its Application in Nano Crystallography
In this article a review on the definition of the X- ray transform and some ofits applications in Nano crystallography is presented. We shall show that the X- raytransform is a special case of the Radon transform on homogeneous spaces when thetopological group E(n)- the Euclidean group - acts on ℝ2 transitively. First someproperties of the Radon transform are investigated then the relationship ...
متن کاملBeyond crystallography: diffractive imaging using coherent x-ray light sources.
X-ray crystallography has been central to the development of many fields of science over the past century. It has now matured to a point that as long as good-quality crystals are available, their atomic structure can be routinely determined in three dimensions. However, many samples in physics, chemistry, materials science, nanoscience, geology, and biology are noncrystalline, and thus their th...
