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…
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…
