Attosecond Polarisation Modulation of X-ray Radiation in a Free Electron Laser
J. Morgan, B. W. J. McNeil
A new method to generate short wavelength Free Electron Laser output with modulated polarisation at attosecond timescales is presented. Simulations demonstrate polarisation switchi…
Free Electron Laser Generation of X-Ray Poincaré Beams
Jenny Morgan, Erik Hemsing, Brian W. J. McNeil +1
An optics-free method is proposed to generate X-ray radiation with spatially variant states of polarization via an afterburner extension to a Free Electron Laser (FEL). Control of…
Two-Colour Free Electron Laser with Wide Frequency Separation using a Single Monoenergetic Electron Beam
L. T. Campbell, B. W. J. McNeil, S. Reiche
Studies of a broad bandwidth, two-colour FEL amplifier using one monoenergetic electron beam are presented. The two-colour FEL interaction is achieved using a series of undulator m…
Towards Zeptosecond-Scale Pulses from X-Ray Free-Electron Lasers
D. J. Dunning, B. W. J. McNeil, N. R. Thompson
The short wavelength and high peak power of the present generation of free-electron lasers (FELs) opens the possibility of ultra-short pulses even surpassing the present (tens to h…
Few-Cycle Pulse Generation in an X-Ray Free-Electron Laser
D. J. Dunning, B. W. J. McNeil, N. R. Thompson
A method is proposed to generate trains of few-cycle x-ray pulses from a Free-Electron Laser (FEL) amplifier via a compact 'afterburner' extension consisting of several few-period…
Unaveraged three-dimensional modelling of the FEL
C. K. W. Nam, P. Aitken, B. W. J. McNeil
A new three dimensional model of the FEL is presented. A system of scaled, coupled Maxwell Lorentz equations are derived in the paraxial limit. A minimal number of limiting assumpt…
