Optimizing the interaction geometry of inverse Compton scattering x-ray sources
C. W. Sweers, O. J. Luiten
Inverse Compton scattering (ICS) is a promising method for generating coherent and tunable x-rays in a compact setup. In this paper, we present a theoretical framework describing t…
First x-rays from a compact and tunable LINAC-based Compton scattering source
I. J. M. van Elk, C. W. Sweers, D. F. J. Nijhof +7
In this paper, we present the first measurements of x-rays produced with a compact, narrowband, and tunable inverse Compton scattering-based x-ray source, developed at Eindhoven Un…
RF acceleration of ultracold electron bunches
D. F. J. Nijhof, T. C. H. de Raadt, J. V. Huijts +3
The ultrafast and ultracold electron source, based on laser cooling and trapping of an atomic gas and its subsequent near-threshold photoionization, is capable of generating electr…
Design and optimization of a 100 keV DC/RF ultracold electron source
D. F. J. Nijhof, P. H. A. Mutsaers, O. J. Luiten
An ultracold electron source based on near-threshold photoionization of a laser-cooled and trapped atomic gas is presented in this work. Initial DC acceleration to 10 keV and…
From ultracold electrons to coherent soft X-rays
J. G. H. Franssen, B. H. Schaap, T. C. H. de Raadt +3
Electromagnetic radiation in the soft x-ray spectral range ( wavelengths or photon energies) is rapidly gaining importance in both fundamental rese…
Gigahertz repetition rate thermionic electron gun concept
W. F. Toonen, X. F. D. Stragier, P. H. A. Mutsaers +1
We present a novel concept for the generation of gigahertz repetition rate high brightness electron bunches. A custom design 100 kV thermionic gun provides a continuous electron be…
Compact ultracold electron source based on a grating magneto optical trap
J. G. H. Franssen, T. C. H. de Raadt, M. A. W. van Ninhuijs +1
The ultrafast and ultracold electron source, based on near-threshold photoionisation of a laser-cooled and trapped atomic gas, offers a unique combination of low transverse beam em…
Time-of-Flight Electron Energy Loss Spectroscopy by Longitudinal Phase Space Manipulation with Microwave Cavities
W. Verhoeven, J. F. M. van Rens, W. F. Toonen +3
The possibility to perform high-resolution time-resolved electron energy loss spectroscopy has the potential to impact a broad range of research fields. Resolving small energy loss…
Theory and particle tracking simulations of a resonant radiofrequency deflection cavity in TM mode for ultrafast electron microscopy
J. F. M. van Rens, W. Verhoeven, J. G. H. Franssen +5
We present a theoretical description of resonant radiofrequency (RF) deflecting cavities in TM mode as dynamic optical elements for ultrafast electron microscopy. We first…
Improving temporal resolution of ultrafast electron diffraction by eliminating arrival time jitter induced by radiofrequency bunch compression cavities
J. G. H. Franssen, O. J. Luiten
The temporal resolution of sub-relativistic ultrafast electron diffraction (UED) is generally limited by radio frequency (RF) phase and amplitude jitter of the RF lenses that are u…
Ultrafast electron diffraction using an ultracold source
M. W. van Mourik, W. J. Engelen, E. J. D. Vredenbregt +1
We present diffraction patterns from micron-sized areas of mono-crystalline graphite obtained with an ultracold and ultrafast electron source. We show that high spatial coherence i…
Compression of sub-relativistic space-charge-dominated electron bunches for single-shot femtosecond electron diffraction
T. van Oudheusden, P. L. E. M. Pasmans, S. B. van der Geer +3
We demonstrate compression of 95 keV, space-charge-dominated electron bunches to sub-100 fs durations. These bunches have sufficient charge (200 fC) and are of sufficient quality t…
Coherent radiation reaction effects in laser-vacuum acceleration of electron bunches
P. W. Smorenburg, L. P. J. Kamp, G. A. Geloni +1
The effects of coherently enhanced radiation reaction on the motion of subwavelength electron bunches in interaction with intense laser pulses are analyzed. The radiation reaction…
Transverse self-fields within an electron bunch moving in an arc of a circle
Gianluca Geloni, Jan Botman, Jom Luiten +5
As a consequence of motions driven by external forces, self-fields (which are different from the static case) originate within an electron bunch. In the case of magnetic external f…
