Accurate time zero determination in an ultrafast transmission electron microscope without energy filter

Marcel Drabbels, Ulrich Lorenz, Pavel Olshin, Jonathan Mark Voss

In this manuscript, we describe a simple and accurate method for finding the temporal overlap of the laser pump and electron probe pulse in ultrafast TEM. Our approach is based on the observation that the outline of a nanoparticle blurs at time zero, a phe ...
