In July, AMO users at the LCLS experimented with a novel piece of technology that aims to make the world's quickest X-ray pulses even quicker. Paul Emma and his team suggested inserting a thin piece of slotted aluminum foil, creating a barrier with a narrow door in the middle. Only the electrons with a direct path through the door contribute to the laser pulse, while the electrons that hit the foil are scattered.
