Radio frequency acceleration and manipulation of ultra-cold electron bunches

Research output: Contribution to conferencePosterAcademic

Abstract

We are developing an ultra-fast and ultra-cold electron source based on a grating magneto optical trap, RF acceleration and RF (de-) compression techniques. The electrons will be created by near-threshold, femtosecond
photoionization of a laser-cooled and trapped gas. The electron cloud is extracted from the plasma by a DC electric field and is further accelerated to energies of 100s keV by means of radio frequency acceleration techniques. This is possible while maintaining the electron beam quality, electron source temperatures of 10 K[1]. The setup can be used to create ultra-short
electron bunches (i.e. 100 fs) by applying RF compression techniques. This makes the source ideal for time resolved pumpprobe crystallography of macromolecules. Secondly, the energy chirp can be removed by RF decompression techniques, resulting in low energy spread electron pulses. This
also makes the source a viable candidate for electron microscopy and coherent imaging.
