Abstract

We are developing microwave cavities to chop a low-emittance electron beam into 100 fs bunches at a repetition rate of 3 GHz. Accurately synchronized to a modelocked laser, these bunches can be used for ultrafast time-resolved TEM [1].
We show recently measured time-of-flight femtosecond electron energy loss spectra (ToF-FEELS) of graphite measured in a horizontal SEM-based setup using a second ‘streak’ cavity. With this cavity we have directly measured an electron pulse length of 2.7 ps and an EELS energy resolution of 12 eV.
Currently we use this setup to study the ponderomotive scattering of electron
bunches off a standing wave of high intensity laser light. At the moment of writing we have already achieved the spatial and temporal overlap of two 30-fs laser pulses. If successful, we plan to study diffraction of electrons on a standing wave of light, the so-called Kapitza-Dirac effect.
