High 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 کاملHigh Current and High Brightness Electron Sources
The development of high current, high brightness electron guns is critically important for free-electron laser and energy recovery linear-accelerator light source facilities. In this paper, we will review the technical requirements of such projects and the status of on-going research throughout the community including results of emittance measurements and high current beam performance.
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 Beams from a Multi- Filamentary Niobium-tin Photocathode
High-brightness electron sources are of fundamental interest for particle accelerators and modern free electron lasers. Inspired by the micro-structure of field emitter arrays [1,2] we report on a new type of metallic photo-cathode consisting of thousands of Nb3Sn micro-columns. With this metallic photocathode we could demonstrate quantum efficiencies up to 0.5% under stable operation [3,4]. Pr...
