Measuring the Electron's Speed

Caption

A laser pulse (red) and an extreme ultraviolet attosecond pulse (violet, 1 as=10^-18 s) hit a surface made of a few layers of magnesium atoms (dark blue) which is on top of a tungsten crystal lattice (green). After the XUV pulse has released electrons from the inner core of the tungsten atoms the physicists determine the time the electrons need for penetrating the magnesium layers by applying the NIR laser pulse.
