High-throughput, high-brightness, ultrashort 90 keV electrons at 40 kHz
K. Amini, T. C. H. de Raadt, J. G. H. Franssen +3
Radiofrequency-compressed keV electron sources for ultrafast electron diffraction (UED) face competing demands: short pulses require low charge, yet weak scatterers demand high flu…
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…
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…
Energy spread of ultracold electron bunches extracted from a laser cooled gas
J. G. H. Franssen, J. M. Kromwijk, E. J. D. Vredenbregt +1
Ultrashort and ultracold electron bunches created by near-threshold femtosecond photoionization of a laser-cooled gas hold great promise for single-shot ultrafast diffraction exper…
Pulse length of ultracold electron bunches extracted from a laser cooled gas
J. G. H. Franssen, T. L. I. Frankort, E. J. D. Vredenbregt +1
We present measurements of the pulse length of ultracold electron bunches generated by near-threshold two-photon photoionization of a laser-cooled gas. The pulse length has been me…
