The instrument used an initial pump pulse of light to excite electrons and generate excitons. This was rapidly followed by a second pulse of light that used extreme ultraviolet photons to kick the electrons within excitons out of the material and into the vacuum of an electron microscope. The electron microscope then measured the energy and angle that the electrons left the material.
