Autor: D. F. J. Nijhof, T. C. H. de Raadt, J. V. Huijts, J. G. H. Franssen, P. H. A. Mutsaers, O. J. Luiten

Publikováno v: Structural Dynamics, Vol 10, Iss 5, Pp 054303-054303-8 (2023)

The ultrafast and ultracold electron source, based on laser cooling and trapping of atomic gas and its subsequent near-threshold two-step photoionization, is capable of generating electron bunches with a high transverse brightness at energies of roug

Pulse length of ultracold electron bunches extracted from a laser cooled gas

Autor: J. G. H. Franssen, T. L. I. Frankort, E. J. D. Vredenbregt, O. J. Luiten

Publikováno v: Structural Dynamics, Vol 4, Iss 4, Pp 044010-044010-15 (2017)

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 measured using a resonant 3 GHz deflecting cavity in TM110 mode. We have

Improving temporal resolution of ultrafast electron diffraction by eliminating arrival time jitter induced by radiofrequency bunch compression cavities

Autor: J. G. H. Franssen, O. J. Luiten

Publikováno v: Structural Dynamics, Vol 4, Iss 4, Pp 044026-044026-10 (2017)

The temporal resolution of sub-relativistic ultrafast electron diffraction (UED) is generally limited by the radio frequency (RF) phase and amplitude jitter of the RF lenses that are used to compress the electron pulses. We theoretically show how to

Compact ultracold electron source based on a grating magneto-optical trap

Autor: J. G. H. Franssen, T. C. H. de Raadt, M. A. W. van Ninhuijs, O. J. Luiten

Publikováno v: Physical Review Accelerators and Beams, Vol 22, Iss 2, p 023401 (2019)

The ultrafast and ultracold electron source, based on near-threshold photoionization of a laser-cooled and trapped atomic gas, offers a unique combination of low transverse beam emittance and high bunch charge. Its use is however still limited becaus
