Soft X-rays and Extreme Ultraviolet Radiation: Principles and.

1.1 (a) Confirm that for a photon energy h ω, with corresponding wavelength λ in vacuum, the two are related by eV nm 1239.842 ⋅ = ⋅ λ ω h Values for physical constants are given in Appendix A, page 419. (b) What wavelength in nm corresponds to photons of energy 543.1 eV? (c) What wavelengths in vacuum are associated with the K and L-absorption edges of neon, chlorine, cobalt, and ruthenium? 1....

Progress toward a Soft X-ray Fel

The recent successes in operating FELs from the far infrared to the visible and near UV [1], together with a better understanding of the physics and technology of these systems, are leading us to explore again the possibility of using FELs to produce coherent radiation in the XUV region, at wavelength shorter than 100 nm . In this paper we derive a set of scaling laws, which we will use to stud...

Comparison between a FEL amplifier and oscillator

Previous experiments with the Raman FEL, situated at the Twente University, showed that the output was influenced by the rather strong increase of the current density with time . The field emission diode has been modified to produce a more constant current pulse to simplify the analysis of the measurements . This resulted in a lower current density of the electron beam . With this new diode two...
