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…
Performance predictions for a laser intensified thermal beam for use in high resolution Focused Ion Beam instruments
S. H. W. Wouters, G. ten Haaf, R. P. M. J. W. Notermans +4
Photo-ionization of a laser-cooled and compressed atomic beam from a high-flux thermal source can be used to create a high-brightness ion beam for use in Focus Ion Beam (FIB) instr…
Polarization effects on the effective temperature of an ultracold electron source
W. J. Engelen, D. J. Bakker, O. J. Luiten +1
The influence has been studied of the ionization laser polarization on the effective temperature of an ultracold electron source, which is based on near-threshold photoionization.…
Analytical Model of an Isolated Single-atom Electron Source
W. J. Engelen, E. J. D. Vredenbregt, O. J. Luiten
An analytical model of a single-atom electron source is presented, where electrons are created by near-threshold photoionization of an isolated atom. The model considers the classi…
Measurement of the temperature of an ultracold ion source using time-dependent electric fields
N. Debernardi, M. P. Reijnders, W. J. Engelen +4
We report on a measurement of the characteristic temperature of an ultracold rubidium ion source, in which a cloud of laser-cooled atoms is converted to ions by photo-ionization. E…
