Samenvatting
In collaboration with FEI Company, we are studying the possi-
bility of using microwave TM110 streak cavities in combination
with a slit, to chop a continuous electron beam into 100 fs elec-
tron bunches.We have shown that this can be done with minimal
increase in transverse emittance and longitudinal energy spread.
Furthermore, these bunches are created at a repetition rate of 3
GHz. Accurately synchronized to a mode-locked laser system,
this allows for high-frequency pump-probe experiments with the
beam quality of high-end electron microscopes.
At Eindhoven University of Technology, we will soon implement
such a cavity in a 200 keV Tecnai, which should result in high-
frequency ultrafast (S)TEM with sub-ps time-resolution while
maintaining the atomic spatial resolution of the TEM.
