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 کاملHigh Brightness Sources for Colliders
Different possible sources are considered and the. importance of the gun for linear colliders discussed. Low emittance electron guns suitable for SLC are available now and we discuss current work that could also provide high polarization. The relative merits of 7, I?* and $* are discussed and how the next linear collider (NLC) naturally provides both e'* and f. Particular emphasis was placed on...
متن کاملHigh Brightness Electron Sources
The production of unprecedentedly high brightness electron beams is a critical aspect of many applications, from free-electron lasers to advanced accelerators. The preferred method for obtaining these beams is the radiofrequency photoinjector. The physics and technology aspects of this device are reviewed here, along prospects for future progress in high-brightness beam development.
متن کاملAn X-ray polarimeter for hard X-ray optics
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays. We calculated the sensitivity with Neon and Argon based mixtures at high pressure with thick absorption gap: placing the MPGC at focus of a next generation multi-layer ...
