An x-ray regenerative amplifier free-electron laser with a step-tapered-undulator
Henry P. Freund, P. J. M. van der Slot, P. G. O'Shea
Regenerative amplifier x-ray free-electron lasers constitute alternative configurations for fourth generation light sources which are typically operated in self-amplified spontaneo…
Efficiency enhancement in regenerative amplifier free-electron lasers using a tapered undulator
Henry Freund, Peter van der Slot, Patrick O'Shea
Recent progress in short wavelength free-electron lasers extending from the extreme ultraviolet through the x-ray regime have opened new avenues for industrial and research applica…
Analysis of Ultra-Short Bunches in Free-Electron Lasers
Lawrence Campbell, Henry Freund, James Henderson +3
Free-electron lasers (FELs) operate at wavelengths from millimeter waves through hard x-rays. At x-ray wavelengths, FELs typically rely on self-amplified spontaneous emission (SASE…
An X-Ray Regenerative Amplifier Free-Electron Laser Using Diamond Pinhole MIrrors
Henry P. Freund, Peter van der Slot, Yuri Shvyd'ko
Free-electron lasers (FELs) have been built ranging in wavelength from long-wavelength oscillators using partial wave guiding through ultraviolet through hard x-ray FELs that are e…
Studies of a Terawatt X-Ray Free-Electron Laser
H. P. Freund, P. J. M. van der SLot
The possibility of constructing terawatt (TW) x-ray free-electron lasers (FELs) has been discussed using novel superconducting helical undulators [5]. In this paper, we consider th…
