We report the design and implementation of a table-top apparatus for Ultrafast Electron Diffraction capable of experiments in both transmission and reflection geometry with electron packets of 30 keV. The electron pulse properties in terms of charge per pulse, transverse spot-size and temporal duration on the sample can be controlled with the use of radiofrequency technology combined with a set of electron optics. The characterization of the beam is performed via a lightelectrons cross-correlation experiment and we demonstrate an overall temporal resolution around 300 fs for bunches containing up to 105 electrons at 20 kHz repetition rate. © 2014 OSA.

Abstract
We report the design and implementation of a table-top apparatus for Ultrafast Electron Diffraction capable of experiments in both transmission and reflection geometry with electron packets of 30 keV. The electron pulse properties in terms of charge per pulse, transverse spot-size and temporal duration on the sample can be controlled with the use of radiofrequency technology combined with a set of electron optics. The characterization of the beam is performed via a lightelectrons cross-correlation experiment and we demonstrate an overall temporal resolution around 300 fs for bunches containing up to 105 electrons at 20 kHz repetition rate. © 2014 OSA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
