XLEAP Experiment (IMAGE)
Caption
Schematic of the XLEAP experiment at SLAC's Linac Coherent Light Source (LCLS) X-ray laser. LCLS sends bunches of high-energy electrons (green) through an undulator magnet, where electron energy gets converted into extremely bright X-ray pulses (blue) of a few femtoseconds, or millionths of a billionth of a second. In the XLEAP configuration, electron bunches pass two additional sets of magnets (wiggler and chicane) that shape each electron bunch into an intense, narrow spike containing electrons with a broad range of energies. The spikes then produce attosecond X-ray pulses in the undulator. The XLEAP team also developed a customized pulse analyzer (right) to measure the extremely short pulse lengths.
