Electron Beam Pulser (IMAGE) DOE/Brookhaven National Laboratory Caption The electron beam pulser (enlarged in the top right image) can be retrofit into existing commercial transmission electron microscopes to turn a normally continuous waveform of electrons into a pulsed beam for stroboscopic ultrafast experiments. The purple box shows a pulsed beam with a time separation of 100 picoseconds.
