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…
Controlled density-downramp injection in a beam-driven plasma wakefield accelerator
Alexander Knetsch, Bridget Sheeran, Lewis Boulton +26
This paper describes the utilization of beam-driven plasma wakefield acceleration to implement a high-quality plasma cathode via density-downramp injection in a short injector stag…
Nanostructure Accelerators: Novel concept and path to its realization
A. Sahai, M. Golkowski, F. Zimmermann +3
TeV/m acceleration gradients using crystals as originally envisioned by R. Hofstadter, an early pioneer of HEP, have remained unrealizable. Fundamental obstacles that have hampered…
Arc-Like Variable Bunch Compressors
Peter H. Williams, Gustavo Pérez-Segurana, Ian R. Bailey +3
Electron bunch compressors formed of achromat arcs have a natural advantage over the more commonly used chicane compressors in that linearisation of the longitudinal phase space is…
Guiding of high-intensity laser pulses in 100mm-long hydrodynamic optical-field-ionized plasma channels
A. Picksley, A. Alejo, J. Cowley +11
Hydrodynamic optically-field-ionized (HOFI) plasma channels up to 100mm long are investigated. Optical guiding is demonstrated of laser pulses with a peak input intensity of $6\tim…
The Laser-hybrid Accelerator for Radiobiological Applications
G. Aymar, T. Becker, S. Boogert +37
The `Laser-hybrid Accelerator for Radiobiological Applications', LhARA, is conceived as a novel, uniquely-flexible facility dedicated to the study of radiobiology. The technologies…
Experimental Study of Wakefields Driven by a Self-Modulating Proton Bunch in Plasma
M. Turner, P. Muggli, the AWAKE Collaboration
We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growt…
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…
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…
Resonant excitation of very high gradient plasma wakefield accelerators by optical-period bunch trains
P. Manwani, N. Majernik, J. B. Rosenzweig
Using a periodic electron beam bunch train to resonantly excite plasma wakefields in the quasi-nonlinear (QNL) regime has distinct advantages over employing a single, higher charge…
Implications of beam filling patterns on the design of recirculating Energy Recovery Linacs
S. Setiniyaz, R. Apsimon, P. H. Williams
Recirculating energy recovery linacs are a promising technology for delivering high power particle beams (GW) while only requiring low power (kW) RF sources. This is ac…
