Reference work 2020Latest edition discovery of the nineteenth century had such an impact on science and technology as Wilhelm Conrad Röntgen’s seminal discovery of X-rays in the year 1895. X-ray tubes soon became established as excellent instruments for numerous applications in medicine, biology, materials science and testing, chem

Echo-Enabled Harmonic Generationy, and flexibility. Unlike HGHG however, EEHG can access much higher harmonics in a single FEL amplification stage, and can produce cleaner FEL spectra that are less sensitive to initial electron beam distortions. Here we review the EEHG concept, the distinguishing features, recent experiments, and known challenges.

Brilliant Light Sources Driven by Laser-Plasma Accelerators an introduction to the basic physics of laser-plasma acceleration and its recent development will be given, followed by a brief discourse on the theory of free-electron lasers. Based on this, we discuss the challenges arising when designing a laser-plasma-based free-electron laser.

Ultrashort Pulses from Synchrotron Radiation Sourceseconds, however, is insufficient to investigate ultrafast processes on the atomic scale. On the other hand, lasers provide femtosecond pulses, but only at long wavelengths. To fulfill the demand for radiation with short wavelength and short-pulse duration, laser-based table-top sources were develope
